Vinyl chloride
= Vinyl chloride
{title2=$\mathrm{CH_2=CHCl}$}
<Vinyl chloride> is chloroethene, $\mathrm{CH_2=CHCl}$. It is a small <vinylic halide> whose carbon-carbon <double bond> can participate in addition polymerization.
Polymerization converts many <vinyl chloride> molecules into <polyvinyl chloride>, with chlorine-bearing repeating units along the carbon backbone. The resulting polymer has physical properties very different from those of the molecular monomer.
