1,1-DCE is used as a comonomer in the polymerization of vinyl chloride, acrylonitrile, and acrylates. Vinyl chloride, also known as chloroethene in IUPAC nomenclature, is an important industrial chemical chiefly used to produce its polymer, polyvinyl chloride (PVC). ... Acrylonitrile (CH2=CH-C≡N), is a pungent smelling, extremely flammable organic liquid. ... Acrylate monomers are esters that contain vinyl groups, that is, two carbon atoms double bonded to each other, directly attached to the carbonyl carbon. ...

The health effects from exposure to 1,1-DCE are primarily on the central nervous system, including symptoms of sedation, inebriation, convulsions, spasms, and unconsciousness at high concentrations.
