Solution

Neoprene is the polymer of 2-chloro-1,3-butadiene, commonly called chloroprene. Free-radical 1,4-polymerization of chloroprene gives the chloro-substituted polybutadiene chain.

Isoprene gives natural rubber; 1,3-butadiene gives polybutadiene; vinylacetylene is the precursor used to synthesize chloroprene, not the monomer itself.
