An example of biopolymer is 
DNA is a biopolymer.
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.
