A polymer is a chain of the same repeating molecule(s).  Suppose the molecule is represented as A - B - C.  Let A = the head and C = the tail.\n\nA 'head to tail' polymer  would look like:\n\nA - B - C - A - B - C - A - B - C \n\nA 'head to head polymer would look like: \n\nC - B - A - A - B - C\n\nAnd a 'tail to tail' would look like: \n\nA - B - C - C - B - A\n\nNow apply these concepts to the actual structure of Acrylonitrile.\n\nBest wishes.

The monomers are linked by covalent chemical bonds.

1) both are nucleotide polymers\n2) contain cytosine, guanine and adenine\n3) made up of a sugar-phosphate backbone with nitrogenous bases\n4) code for biologically important information\n5) are stable\n6) capable of precise replication\n7) capable of incorporating mutations

If you are referring to - polysaccharides, they are carbohydrates (e.g., starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.

vulcanised rubber is made by heating the rubber with sulphur.(by Charles Goodyear-1838)\nproperties:even in very high temperatures,it will not loose its elasticity, when the force is taken away it resumes its usual shape, the increased ability to carry weight, doesn't corrode easily.\neg:tyres & tubes, corks, rubber pipes, raincoats, slippers\nhope that helped-cheers!

A substance is called an elastomer if it is elastic in nature i.e. it follows Hooke's law. Slime is not an elastomer.

Ok... I was thinking of plastics...my bad..hehe\n\nHere`s some info I found\n\nToday Asia is the main source of natural rubber. Over half of the rubber used today is synthetic, but several million tonnes of natural rubber are still produced annually, and is still essential for some industries, including automotive and military.

It's polystyrene, the polymer formed from styrene (phenylethene).

Yes, DNA is a polymer composed of four different nucleotides. The nucleotides are composed of phosphate and the sugar 2' deoxyribose, which make up the backbone of a molecule of DNA, and one of four nitrogenous bases: adenine (A), guanine (G), thymine (T), and cytosine (C). Bases on opposite DNA strands can form hydrogen bonds (A with T, and G with C), which hold the double-stranded molecule together. Polymerization of DNA occurs through the enzyme DNA polymerase, which catalyzes the synthesis of one of the DNA strands using the other strand as a template.

The response of polymers differs from one to another and beyond doubt it is vary complicated. Fortunately there are some references modeling this behavior. If you want more on this send me your questions at david_blear@yahoo.com

In addition polymerization, many small units of the same type called monomers combine to form a long chain of a polymer, with simple covalent bonds and no loss of a molecule. For this polymerization to occur, the monomer must have a C=C double bond, because polymerization takes place across the double bond E.g. formation of polyethene from ethene; polypropene from propene etc.\n\nIn condensation polymerization, two same monomers or two different monomers combine to form a polymer, with the elimination of a small molecule like H20. Here, a double bond need not be present. E.g. formation of proteins from aminoacids etc.

condensation polymerization involves removing a water molecule for every bond formed between the monomers.\n\naddition polymerization involves breaking double bonds to join the monomers

polymer, chemical compound with high molecular weight consisting of a number of structural units linked together by covalent bonds (see chemical bond). The simple molecules that may become structural units are themselves called monomers; two monomers combine to form a dimer, and three monomers, a trimer. A structural unit is a group having two or more bonding sites. A bonding site may be created by the loss of an atom or group, such as H or OH, or by the breaking up of a double or triple bond, as when ethylene, H2C[double bond]CH2, is converted into a structural unit for polyethylene, -H2C-CH2-. In a linear polymer, the structural units are connected in a chain arrangement and thus need only be bifunctional, i.e., have two bonding sites. When the structural unit is trifunctional (has three bonding sites), a nonlinear, or branched, polymer results. Ethylene, styrene, and ethylene glycol are examples of bifunctional monomers, while glycerin and divinyl benzene are both polyfunctional. Polymers containing a single repeating unit, such as polyethylene, are called homopolymers. Polymers containing two or more different structural units, such as phenol-formaldehyde, are called copolymers. All polymers can be classified as either addition polymers or condensation polymers. An addition polymer is one in which the molecular formula of the repeating structural unit is identical to that of the monomer, e.g., polyethylene and polystyrene. A condensation polymer is one in which the repeating structural unit contains fewer atoms than that of the monomer or monomers because of the splitting off of water or some other substance, e.g., polyesters and polycarbonates. Many polymers occur in nature, such as silk, cellulose, natural rubber, and proteins. In addition, a large number of polymers have been synthesized in the laboratory, leading to such commercially important products as plastics, synthetic fibers, and synthetic rubber. Polymerization, the chemical process of forming polymers from their component monomers, is often a complex process that may be initiated or sustained by heat, pressure, or the presence of one or more catalysts.

Carbohydrates: include sugars and their polymers. They include monosaccharides disaccharides, and polysaccharides. The monosaccharide is a monomer, the disaccharide is a polymer,and the polysaccharides are macromolecules.\n \nMonosaccharides: The basic formula (CH2O)\nExamples: triose sugars, 3 carbons, glyceraldehyde and dihydroxyacetone; pentose sugars. 5 carbons. ribose, deoxyribose, and ribulose; hexose sugars, 6 carbons, glucose, galactose, and fructose.\n     \n\n \n \nDisaccharides: These are double sugars with the formula C12H22O11. Notice that one molecule of water is missing from the formula. The covalent bond holding the two monomers together is called a 1-4 or 1-2 glycoside linkage. Examples: sucrose = glucose + fructose. maltose = glucose + glucose, and lactose = glucose + galactose.\n \n     \n\n \nPolysaccharides: The basic formula is ( C6H10O5)n . These are macromolecules capable of acting as structural or storage molecules.\n \nStorage Polysaccharides: Starch is a plant storage polysaccharide that is composed entirely of glucose joined by @1-4 glycoside linkages. amylose is the simplest form of starch. amylopectin is more complex and is branched. Glycogen is an animal starch stored in the liver and muscles of vertebrates. It is more highly branched than amylopectin.\n \nStructural Polysaccharides: Cellulose and chitin are examples of structural polysaccharides.\nCellulose is the most abundant organic compound on earth. It is made of glucose, like starch, but they differ in the type of 1-4 linkage. Instead of an @ linkage as in starch cellulose contains a B 1-4 linkage.\nThis causes the polysaccharide to take on a step arrangement and not a linear one like in starch.\nEnzymes find it difficult to brake the B 1-4 linkage.
