THERMOPLASTIC COMPOSITION PREPARED BY SYNERGISTICALLY COMBINING DILAURYL THIODIPROPIONATE WITH TRIS(NONYLPHENYL) PHOSPHITE

摘要

PURPOSE: To obtain the subject composition stabilized without using any primary antioxidant and being useful as an engineering plastic, or the like by adding a specified stabilizer to a vinylaromatic/alkenyl cyanide diene rubber graft copolymer. ;CONSTITUTION: A synergistic stabilizer (B) containing a thioester and an organic phosphite is added to a vinylaromatic/alkenyl cyanide/diene rubber graft copolymer (A) and mixed therewith. The (disc)coloration due to a phenolic antioxidant or the like can be prevented.;COPYRIGHT: (C)1995,JPO
