Vinyl polymers are derived from vinyl monomers (i.e, small molecules containing carbon-carbon double bonds). Vinyl polymers are the largest family of polymers. Vinyl polymerization is the linking together of unsaturated compounds (monomers) to make chain polymers as indicated through the scheme:

n[CH2ÓCHX] → –[-CH2[CHX-]n-

The α-carbon atom (CH2ÓCXY) substituted vinyl monomers produce highperformance polymers but the substances which are substituted on both carbon atoms of the ethylinic bond (RCHÓCHR1) show reduced polymerization.
