Vedclass · Answer

(A) Neoprene is a synthetic rubber (elastomer) formed by the free radical polymerization of chloroprene ($2-$chloro$-1,3-$butadiene).It is a homopolymer,not a copolymer,because it is formed from a single type of monomer unit.It is used to prepare hose pipes for the transport of gasoline due to its resistance to oils and chemicals.The monomer chloroprene $(CH_2=CCl-CH=CH_2)$ is an unsaturated compound.Therefore,the statement that it is a copolymer is false.
