Starch

B

Nucleic acid

C

Polystyrene

D

Protein

Text Solution

Verified by Experts

The correct Answer is:
C

Polystyrene is an example of chain growth polymer. In chain growth polymerisation, the molecules of the same monomer of different monomers add together on a larger scale to form a polymer

  • Polymers are made up of small molecules called monomers. Polymer which are formed by one type of monomer is called homopolymer and which are formed by more than one type of monomers are called co-polymers. Natural polymers are biodegradable whereas synthetic polymers may or may not be. Addition or chain growth polymerization involves the repeated addition of monomers to the polymer chain. The monomers are unsaturated compounds and this type of polymerization takes place by ionic (cationic or anionic) as well as free radical mechanism. Condensation or step growth polymerization involves a series of condensation reactions between twomonomers. Each monomer normally contains two functional groups. Branch chain polymers may be condensation or addition but cross linked polymers are always condensation polymers. Which of the following is a chain growth polymer?

    A
    Polystryrene
    B
    PTFE
    C
    Polybutadiene
    D
    All of these
