Title (EN) POLYMERIC COMPOSITIONS BASED ON IMPACT RESISTANT VINYL AROMATIC POLYMERS.
(FR) COMPOSITIONS POLYMERIQUES A BASE DE POLYMERES VINYLAROMATIQUES RESISTANTS AUX CHOCS
Abstract: front page image
(EN)Polymeric compositions containing: a) 70-97% by weight of a vinyl aromatic polymer modified with rubber; b) 3-30% by weight of a vinyl aromatic polymer with a syndiotactic structure having a melting point higher 15 than 255°C; c) 0-10% by weight with respect to (a) + (b) of a poly­ phenylene ether; and d) 0-10% by weight with respect to (a) + (b) of an elas­ tourer selected from block copolymers consisting of at least one non-elastomeric polymeric block of a vinyl aromatic monomer and at least one elastomeric block based on a 1,3-conjugated diene.
(FR)L'invention concerne des compositions polymériques contenant: a) 70 à 97 % en poids d'un polymère vinylaromatique modifié par caoutchouc; b) 3 à 30 % en poids d'un polymère vinylaromatique présentant une structure syndiotactique dont le point de fusion est supérieur à 255 °C; c) 0 à 10 % en poids, relativement aux proportions a) + b), d'un poly(phénylène éther); et d) 0 à 10 % en poids, relativement aux proportions a) + b), d'un élastomère choisi parmi des copolymères séquencés constitués d'au moins un bloc polymérique non élastomère d'un monomère vinylaromatique et d'au moins un bloc élastomère basé sur un diène 1,3-conjugué.
