Why is polymer bouncy?
Rubber is especially bouncy because of its wrinkled chains between sparse crosslinks. The crosslinking prevents the material being a liquid. The chains become almost linear when the material is stretched. The restoring force is a statistical phenomenon: There are many more wrinkled conformations than "almost linear" ones. The "need" for many conformations increases with temperature as does the restoring force.
What does PEX stands for in DU results?
PEX is produced with crosslinked polyethylene. Crosslinking is obtained through a chemical process that increases the bonds between macromolecules to form a more complex structure than the normal polyethylene. Due to the crosslinking, the polyethylene's performance is greatly enhanced still maintaining the excellent properties of thermoplastics. for more details you may visit on this link : http://www.ardipex.com/pex-pipes.php
What is the structure of divinylbenzene cross-linked polystyrene solid support?
the styrene portion creates linear polymeric structures since styrene is monofunctional. The divinylbenzene is difunctional, so where it is indorporated in a styrene chain, there is one functional group left to react. When this happens in the making of another polystyrene chain, the result is a crosslinked structure. The proportion of divinylbenzene controls the amount of crosslinking. This translates into more or less porosity (allowed permeation in the final polymer) with less or more divinylbenzene.
What is a large molecule that is formed by more than 5 monomers?
A polymer is a large molecule that is formed by more than 5 monomers. Polymers are also found in macromolecules.
What is plastic cement?
It is cement where a polymer such as SBR latex or PVA emulsion or other polymer is added to plasticize and make the cement more flexible.
What is protein crosslinking?
This protein crosslinking consists of between primary amine (lysine) and sulfhydryl (cysteine) groups of proteinsand other molecules; which are available with different lengths and types of spacer arms.
What is the importance of crosslinking and chains in polymers?
It affects the properties of a polymer by it being "combine" with sodium borate.

What is a non conducive polymer?
You may be thinking of a non conductive polymer, which is a plastic. It is also possible for a polymer to be non conducive, but if so, then you have to say to what is the polymer not conducive. Be more specific.
What forms a polymer when two or more join together?
When two or more join together a polymer forms a molecule.
What describes any polymer that can be stretched more than two hundred percent?
Resorbable polymer
How can you make a flexible polymer more rigid?
At the design stage adding molecules/monomers with more rings than chains will make the polymer more rigid. If this option is not available, adding fiber or particles or fillers is the usual technique. You can make a stiff polymer more flexible by adding plasticizers, but going the other way is more difficult. Technically speaking the polymer itself isn't changing, but the material overall will be more rigid than the polymer matrix due to the fiber support.

What is the difference between a cross linked polymer and a polymer?
Cross linked polymers are made of 2 or more monomers whereas a simple polymer is made up of a single monomer.

What does a plasticiser allow polymer chains to do?
a plasticiser allows polymer chains to slide over each other more easily :)
