Which one of the following is a chain growth polymer?
Options
- AStarch
- BNucleic acid
- CPolystyrene
- DProtein
Correct answer
C. Polystyrene
Step-by-step solution
Polystyrene is an addition polymer that results when styrene monomers interconnect (polymerization). In the polymerization, the carbon-carbon bond of the vinyl group is broken and a new carbon-carbon bond is formed, attaching to the carbon of another styrene monomer to the chain. Related Theory In chain growth, the polymer chain always grows one monomer at a time. In step growth, the polymer chain doubles with each step. As a result, the rate of growth of the polymer chain is very different in these two cases. Chai
