The displayed formula below shows part of the chain of an addition polymer. (i) Deduce the structural formula of the monomer used to build this polymer. (ii) Describe one chemical property responsible for this type of polymer being a useful material.

Which monomer produces this addition polymer? A. $\ce{CH2=CHCH2CH3}$ B. $\ce{CH3CH=CHCH3}$ C. $\ce{CH2=C(CH3)2}$ D. $\ce{CH2=CHCH=CH2}$

4-Methylstyrene is capable of undergoing polymerization. Draw a section of the resulting polymer chain, showing three repeating units, and state what type of polymerization this is.
