Abstract:
A reinforced thermoplastic composition, consisting essentially of:a) 100-80% by weight of a crystalline syndiotactic polymer of styrene having a degree of syndiotaxy of at least 75%; b) 0-20% by weight of a polyarylene-ether; c) 1-200 parts by weight with respect to 100 parts of (a)+(b), of one or more rigid inorganic fillers; d) 0.01-5 parts by weight, with respect to 100 parts of (a)+(b), of a silanic compound having formula (I): â€ƒwherein R and R1 are, independently from each other, hydrogen or an alkyl radical containing from 1 to 8 carbon atoms; R2 is a hydrolyzable alkoxy group containing from 1 to 6 carbon atoms or a halogen atom; R3 is an alkyl radical containing from 1 to 8 carbon atoms; X is either a radical having the formula: â€ƒor an aromatic or cycloaliphatic or heterocyclic radical, wherein R4 is hydrogen or an alkyl radical containing from 1 to 8 carbon atoms and n is an integer of 1 to 4; m is an integer of 1 to 3.
