PROCESS OF POLYMERIZATION IN EMULSION OF 1-ALKENES AND VINYL ESTERS WITH HIGH CONVERSION AND THEIR USE

New process conditions are described and more particularly emulsion polymerization of compositions which are based on copolymers of vinyl acetate, straight chain a- olefin and an optional third different olefinically-unsaturated co-monomer in which the a- olefin is emulsified prior to the addition i...

Summary:New process conditions are described and more particularly emulsion polymerization of compositions which are based on copolymers of vinyl acetate, straight chain a- olefin and an optional third different olefinically-unsaturated co-monomer in which the a- olefin is emulsified prior to the addition into the polymerization mixture. L'invention porte sur de nouvelles conditions de procédé et plus particulièrement sur la polymérisation en émulsion de compositions qui sont à base de copolymères d'acétate de vinyle, d'a-oléfine à chaîne droite et facultativement d'un troisième comonomère à insaturation oléfinique différent dans laquelle l'a-oléfine est émulsifiée avant l'ajout dans le mélange de polymérisation.
