Abstract
Procedure for the preparation of polyacetovinyl dispersions, particularly by polymerization of vinyl acetate in aqueous dispersion at a conventional temperature, characterized in that the polymerization is carried out in the presence of a) an oxidizing system consisting of peroxides or persuliates; b) a reducing system consisting of one or more mono or bi-carboxylic acids; c) an acetate and/or sulfate of an element of the VIII group of the periodic system; d) a continuously fed alkali or alkaline earth metal bicarbonate and/or acetate in the course of polymerization; e) a modifier selected from aldehydes with a boiling point lower than 70ºC or esters of butyl alcohol with a boiling point higher than 150ºC; f) polyvinyl alcohol.
