Abstract
La présente invention concerne un procédé de polymérisation d'halogénures de vinyle avec des polymères et copolymères d'oléfines et leurs compositions. Un homopolymère amélioré d'halogénure de vinyle ou copolymère amélioré d'halogénure de vinyle contenant jusqu'à 50 % d'un comonomère peut être obtenu par polymérisation en contact avec un homopolymère, copoymère ou terpolymère d'oléfine aliphatique dans un procedé de polymérisation en masse comprenant une polymérisation en masse en une seule étape ou en deux étapes en utilisant une agitation à grande vitesse durant la première étape et une agitation à petite vitesse dans la deuxième étape. Grâce à la polymérisation en présence du polymère ou copolymère d'oléfine, on peut obtenir dans la résine produite une grosseur réduite des particules, une formation réduite de grumeaux, une plus faible viscosité à l'état fondu et une résistance au choc améliorée.The present invention relates to a process for the polymerization of vinyl halides with olefin polymers and copolymers and their compositions. An improved vinyl halide homopolymer or improved vinyl halide copolymer containing up to 50% of a comonomer can be obtained by contact polymerization with an aliphatic olefin homopolymer, copolymer or terpolymer in a polymerization process. A mass comprising one-step or two-step bulk polymerization using high speed agitation during the first step and low speed agitation in the second step. By polymerization in the presence of the olefin polymer or copolymer, reduced particle size, reduced lump formation, lower melt viscosity and improved impact resistance can be obtained in the resin produced.
