Title (EN) PROCESS FOR THE PREPARATION OF POLYMER PARTICLES
(FR) PROCEDE POUR LA PREPARATION DE PARTICULES DE POLYMERE
Abstract: front page image
(EN)Process for the preparation of vinylarene polymer particles, which process comprises mixing a polar polymer capable of absorbing water, with vinylarene monomer; pre-polymerising vinylarene monomer; suspending the pre-polymerised mass; and polymerise the suspended particles further. This case further relates to vinylarene polymer particles containing polar polymer and from more than 3 to 40 wt.% of water, and to foamed articles.
(FR)L'invention concerne un procédé pour la préparation de particules de polymère de vinylarène. Ce procédé consiste à mélanger un polymère polaire pouvant absorber l'eau, avec un monomère de vinylarene, à prépolymériser le monomère de vinylarène, à mettre en suspension la masse prépolymérisée, et à polymériser les particules en suspension. Cette invention concerne, en outre, des particules de polymère de vinylarene contenant un polymère polaire et entre 3 et 40 % en poids d'eau. L'invention traite aussi d'articles moussés.
