Question 37

A materials chemist is checking a proposed structure for an addition polymer used in a protective coating.

StructureFormula
Alkene monomerCH2=CHCH2CH3\text{CH}_2\text{=CHCH}_2\text{CH}_3CH2​=CHCH2​CH3​
Proposed repeating unit[-CH2-CH(CH2CH3)-]n\left[\text{-CH}_2\text{-CH}(\text{CH}_2\text{CH}_3)\text{-}\right]_n[-CH2​-CH(CH2​CH3​)-]n​

Explain how the information shows that the proposed repeating unit could be formed from the alkene monomer by addition polymerisation.
