Abstract
PURPOSE: To prepare a coplymer of chloroprene and an unsaturated nitrile giving the vulcanizate having improved oil resistance, heat resistance and ozone resistance, by carrying out the polymerization in the presence of an emulsifier comprising a disproportionated rosin acid, a naphthalenesulfonic acid derivative, an unsaturated fatty acid salt, polyvinyl alcohol, etc.
CONSTITUTION: The desired polymer is prepared by the emulsion polymerization of 100 parts by weight of a monomer mixture comprising (A) ≥50wt% of chloroprene and (B) an unsaturated nitrile (e.g. acrylonitrile), in the presence of (C) ≥100 parts of water and (D) an emulsifier composition comprising (a) 2W5 parts of a disproportionated rosin acid, (b) 1W3 parts of the water-soluble salt of a naphthalenesulfonic acid-formaldehyde condensate, (c) 0.5W3 parts of a 12W20C unsaturated fatty acid salt (e.g. potassium oleate, etc.) and (d) 0.05W1.0 parts of water-soluble polyvinyl alcohol.
