Abstract

1,167,666. Polymerizing vinyl esters. E. I. DU PONT DE NEMOURS & CO. 16 April, 1968 [13 April, 1967], No. 17975/68. Heading C3P. In the polymerization or copolymerization of vinyl esters followed by stripping off unreacted monomers, a colourless hydrazine compound having at least one nitrogen bonded hydrogen is added before the stripping step as a polymerization inhibitor. Solution in methanol or emulsion technique can be used. The vinyl ester is the acetate, formate, propionate or butyrate and in examples acrylic acid, methacrylic acid, monomethyl maleate or vinyl pyrrolidone is added as comonomer. Hydrazine monoacetate is used as inhibitor. The product is alcoholysed.
