Abstract

Procédé perfectionné pour préparer des matières à mouler thermoplastiques consistant en 40 à 70 parties en poids d'un polycarbonate à base de composés aromatiques hydroxylés et 60 à 30 parties en poids d'un copolymère ABS consistant lui-même en un polymère greffé de 15 à 60 parties en poids d'un mélange de 95 à 50 % en poids de styrène et/ou de méthacrylate de méthyle et 50 à 5 % en poids d'acylonitrile et/ou de méthacrylate de méthyle polymérisé par greffage sur 85 à 40 parties en poids d'un caoutchouc. On dissout ou on met en suspension le polycarbonate et le copolymère ABS séparément dans un solvant organique, on mélange les solutions ou suspensions obtenues, on évapore dans un premier stade la plus grande partie du solvant et on fait passer la matière solide résiduelle dans une vis à évaporation. Le procédé selon l'invention permet de parvenir pour la première fois à des matières à mouler mélangées dans lesquelles la phase continue consiste en polycarbonate bien que celui-ci représente moins de 70 % du poids total.An improved process for preparing thermoplastic molding materials consisting of 40 to 70 parts by weight of a polycarbonate based on aromatic hydroxy compounds and 60 to 30 parts by weight of an ABS copolymer itself consisting of a graft polymer of 15 to 60 parts by weight of a mixture of 95 to 50% by weight of styrene and / or methyl methacrylate and 50 to 5% by weight of acylonitrile and / or methyl methacrylate polymerized by grafting on 85 to 40 parts in weight of a rubber. The polycarbonate and the ABS copolymer are dissolved or suspended separately in an organic solvent, the solutions or suspensions obtained are mixed, most of the solvent is evaporated off in a first stage and the residual solid material is passed through a screw. evaporative. The process according to the invention makes it possible for the first time to achieve mixed molding materials in which the continuous phase consists of polycarbonate although this represents less than 70% of the total weight.
