PROCESS FOR THE PREPARATION OF LATEX OF VINYL ACETATE / ETHYLENE COPOLYMER AND LATEX THUS OBTAINED

摘要

P The invention relates to a process for the preparation of vinyl acetate / ethylene copolymer latex. /P P About 60 to 95% by weight of vinyl acetate is copolymerized with about 40 to 5% by weight of ethylene, in an emulsified medium containing at least one surfactant in an amount of about 1.0 minimum% and approximately 2.0% maximum of the total weight of monomers, a catalyst and a protective colloid, the total weight of surfactant and vinyl acetate being introduced into the medium in delayed portions, before and after the start of the copolymerization. /P P These latexes have improved adhesion properties. /P
