A) Starch
B) Nucleic acid
C) Polystyrene
D) Protein
Correct Answer: C
Solution :
| [c] Chain growth polymerisation requires an initiator (such as organic peroxides) to produce a free radical to which the monomers are added in a chain fashion. Initiators are added in a very small quantities and are decomposed by heat, light or oxidation-reduction reaction to produce reactive species, e.g., free radical. Polystyrene is an example of chain growth polymer because in it styrene molecules are associated in the form of monomer. |
