Abstract

1407181 Polymerization initiator PPG INDUSTRIES Inc 24 Aug 1973 [28 Aug 1972] 40163/73 Heading C3P The polymerization of ethylenically unsaturated monomers is effected in the presence of an initiator comprising in combination a carboxylic anhydride, a percarboxylic acid and an alkaline buffering agent. A further free radical initiator may be present, especially a peroxydicarbonate ester. Examples relate to the suspension polymerization of vinyl chloride.
