Abstract

Abstract A THERMOPLASTIC RESIN COMPOSITION COMPRISING (I) 20 TO 70 PARTS BY WEIGHT OF A COPOLYMER CONSISTING OF 20 TO 50 PARTS BY WEIGHT OF A DIENE TYPE RUBBERY POLYMER HAVING A GEL CONTENT OF AT LEAST 75% AND AN AVERAGE PARTICLE DIAMETER OF AT LEAST 0.2U AND A RESINOUS POLYMER CONSISTING OF 40 TO 60 PARTS BY WEIGHT OF AN AROMATIC VINYL COMPOUND AND 10 TO 30 PARTS BY WEIGHT OF AN UNSATURATED ALIPHATIC NITRILE COMPOUND, THE PROPORTION OF SAID RESINOUS POLYMER CHEMICALLY BONDED TO THE ABOVEMENTIONED RUBBERY POLYMER BEING 15 TO 30 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF THE RUBBERY POLYMER, THE SPECIFIC VISCOSITY OF THE REMAINING UNBONDED RESINOUS POLYMER BEING 0.5 TO 0.9, (II) 30 TO 80 PARTS BY WEIGHT OF A POLYMER HAVING A SPECIFIC VISOCSITY OF 0.45 TO 0.9 WHICH COMPRISES 65 TO 85 PARTS BY WEIGHT OF AN UNVINYL COMPOUND AND 35 TO 15 PARTS BY WEIGHT OF AN UNSATURATED ALIPHATIC NITRILE COMPOUND, (III) 0.1 TO 3 PARTS BY WEIGHT OF A METAL OF A FATTY ACID AND (IV) AT LEAST 0.01 PART BY WEIGHT OF AN ORGANOSILICON COMPOUND. SAID COMPOSITION IS EXCELLENT IN IMPACT RESISTANCE, PROCESSABILITY AND APPEARANCE. WHEN MERELY SUBJECTED TO SIMPLE MELT-EXTRUSION, THE COMPOSITION CAN GIVE A MOLDED ARTICLE WHICH IS FREE FROM SUCH DRAWBACKS AS SEEN IN CONVENTIONAL MOLDED ARTICLES.
