An example of biopolymer is 
A Natural polymer which controls various life process in the body of a organism is called natural biopolymer.
DNA is a natural biopolymer which is a main constituent of chromosomes.
Rubber is a natural polymer but not a natural biopolymer.
Teflon and Nylon-6,6 both are synthetic polymers.
Bakelite is prepared by the reaction between 
Phenol and formaldehyde undergo
condensation polymerisation under two
different conditions to give a cross linked
polymer called bakelite.
In elastomer, intermolecular forces are 
Elastomers are the polymers having very
weak intermolecular forces of attraction
between the polymer chain. The weak forces
permit the polymer to be streched.
Nylon 66 is a polyamide obtained by the reaction of 
Which one of the following is used to make "nonstick" cook-wares ? 
We know that polytetrafluoroethylene or
teflon is a tough material, resistance to heat
and bad conductor of electricity. Therefore
it is used for coating the cookware to make
