An example of biopolymer is: 
Example of Biopolymers:
Bakelite is prepared by the reaction between: 
Phenol and formaldehyde undergo condensation polymerization under two different conditions to give a cross-linked polymer called Bakelite.
Reaction Mechanism for preparation of Bakelite:
In elastomer, intermolecular forces are: 
Elastomers are polymers having very weak intermolecular forces of attraction between the polymer chain, and these weak forces permit the polymer to be stretched.
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, resistant to heat, and a bad conductor of electricity.
Thus, it is used for coating the cookware to make them non-sticky.
Natural rubber is a polymer of: 
Natural rubber is a polymer of isoprene, [CH2 =C(CH3)CH=CH2] i.e. 2-methylbutadiene
CF2 = CF2 is a unit of: 
Which of the following is not correctly matched?
Terylene is prepared by condensing dimethyl terephthalate and ethylene glycol in presence of a weak base, (calcium acetate). Methanol is eliminated during condensation.
Monomer of :

Which of the following statements is false? 
Nylon-66 is an example of the first synthetic fibers produced from simple molecules. It is prepared by condensation polymerization of adipic acid and hexamethylenediamine.
Which one of the following sets forms the biodegradable polymer? [2012 M]
Biodegradable polymer is Nylon-2- Nylon-6 which is copolymer of glycine (H2N – CH2– COOH) and amino caproic acid (H2N–(CH2)5 – COOH).
Which is the monomer of Neoprene in the following? [NEET 2013]
Chloroprene is the monomer of neoprene.
Nylon is an example of: [NEET 2013]
Naturally occurring polyamides are proteins, such as wool and silk.
Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis yielding materials such as nylons, aramids, and sodium poly(aspartate).
