*LoL* you know, you can always use Wikipedia..the link is below in case you don't know Wiki's site =p *LoL*\n\nhttp://en.wikipedia.org/wiki/Polymers\n\nAnyway...HAPPY STUDYING *LoL*

A polymer is a collection of monomers. You could visualise a polymer (just by way of example), as a string of beads - one bead is a monomer, while the whole string of beads is the polymer

Not enough information provided. The density of any carbon fiber product is based apon the requirements of the product and its use. The amount of polymer to fiber ratio is based on that information.

I'll go out on a limb and suppose that you need some very simple projects that can demonstrate polymer properties to the layperson.\n\nPhysics:  \n\nIf you take a rubber band, an elastomer, suspend a weight from it, and gently heat the rubber band with something like a hair drier, you can demonstrate that polymer chains prefer to adopt a random coil configuration rather than a straight, linear configuration. (I'll leave out the basic thermodynamic details so you can delve deeper into the subject.)\n\n\nChemistry:\n\nTo demonstrate the differences in size between polymers and small molecules, look up the size of a single water molecule and then get a piece of foam rubber.  The water molecule's size is on the order of Angstroms, while the foam rubber is essentially one gigantic molecule.\n\nIf you have access to sebacoyl chloride and hexamethylene diamine, you can make Nylon-6 by using equal parts of both reactants.  The polymer forms at the interface of the two liquids, and you can use tweezers to pull the polymer out of the reaction vessel.  NOTE:  Proper safety precautions MUST be followed as both chemicals are irritants. \n\nI've left out sources and a lot of other details so you can research the physics/chemistry of the examples given here.

If you mean at what wavelength does polystyrene have its strongest absorption in the ir, you may find your answer at the link below.\n\nhttp://webbook.nist.gov/chemistry/name-ser.html\n\nHere you can type in a name and find some physical data. Good luck

Its better to get a design engineering guide from one of the plastic raw material suppliers as modifying the melt flow index would change many other properties also. A manufacturer rather than a distributor would probably provide you the information more readily.

Hey buddy  you may take  a  look at this  site which offers  this  kinda  services and explains everything slightly  good:http://www.e1.greatlakes.com/corp/prodserv/jsp/optical_monomers.jsp\n\nThis also:http://industrial-adhesives.globalspec.com/Industrial-Directory/monomer_MSDS_styrene\n\nand  about  acrylic glass:http://en.wikipedia.org/wiki/Polymethyl_methacrylate
