Final answer:
Propene (CH_2=CH-CH_3) undergoes addition polymerization to form a polymer called polypropene or polypropylene, represented as -[-CH(CH3)-]-.
Step-by-step explanation:
The molecule given (CH_2=CH-CH_3) is an example of propene, a type of alkene. In polymer chemistry, propene can undergo a process known as addition polymerization to form a larger molecule called polypropene (also known as polypropylene). This process involves the breaking of the carbon-carbon double bond and the formation of single bonds that link the propene molecules together in a long chain. Here's a simplified representation of the resulting polymer: -[-CH(CH3)-]-
