摘要： THERE ARE PROVIDED HIGH IMPACT STRENGTH THERMOPLASTIC COMPOSITIONS COMPRISING A POLYPHENYLENE ETHER AND A RUBBER MODIFIED POLYSTYRENE RESIN, THE POLYSTYRENE MATRIX IN THE COMPOSITION HAVING AN INTRINSIC VISCOSITY OF AT LEAST 1.0 DECILITERS/GRAM. SUCH COMPOSITIONS, WHICH CONTAIN POLYSTYRENE OF SUBSTANTIALLY HIGHER MOLECULAR WEIGHT THAN HERETOFORE, PROVIDE MOLDED ARTICLES WITH UNEXPECTED IMPROVEMENTS IN IMPACT RESISTANCE, SURFACE APPEARANCE AND RESISTANCE TO AGGRESSIVE SOLVENT SYSTEMS. ALSO PROVIDED ARE HIGH IMPACT COMPOSITIONS, USEFUL PER SE OR FOR BLENDING WITH POLYPHENYLENE ETHERS, COMPRISING POLYBLENDS OF RUBBER DISPERSED IN A POLYSTYRENE MATRIX, THE POLYSTYRENE HAVING AN INTRINSIC VISCOSITY OF AT LEAST 1.0 DECILITERS/GRAM.

摘要： There are provided compositions comprising a polyphenylene ether, a graft copolymer of a diene rubber with a styrene monomer and a normally rigid block copolymer of a vinyl aromatic compound and a conjugated diene. The addition of the normally rigid block copolymer resin to polyphenylene ethers in combination with graft copolymers of a diene rubber and a styrene monomer provides unexpected improvements in toughness in parts molded from the composition. Such properties are improved without substantially impairing glass or surface appearance.

摘要： THERE ARE PROVIDED COMPOSITIONS COMPRISING (A) A POLYPHENYLENE ETHER, (B) A NORMALLY RIGID BLOCK COPOLYMER OF A VINYL AROMATIC COMPOUND AND A CONJUGATED DIENE, AND (C) A GRAFT INTERPOLYMER OF AN ACRYLATE MONOMER AND A DIENE RUBBER. THE THREE-COMPONENT COMPOSITION PROVIDES UNEXPECTED IMPROVEMENTS IN TOUGHNESS IN PARTS MOLDED THEREFROM AND SUCH PROPERTIES ARE IMPROVED WITHOUT SUBSTANTIALLY IMPAIRING GLOSS OR SURFACE APPEARANCE.

摘要： THERE ARE PROVIDED HIGH IMPACT STRENGTH THERMOPLASTIC COMPOSITIONS COMPRISING IN COMBINATION (A) A POLYPHENYLENE ETHER RESIN, (B) A POLYSTYRENE RESIN AND (C) AN INTERPOLYMER OF 30 TO 70 PARTS BY WEIGHT OF A DIENE RUBBER WITH 70 TO 30 PARTS BY WEIGHT OF (I) A VINYL AROMATIC COMPOUND OR (II) A MIXTURE OF A VINYL AROMATIC COMPOUND AND AN ACRYLIC ESTER, THE COMPOSITIONS HAVING A DISPERSED ELASTOMERIC PHASE WITH AT LEAST 85% OF THE NUMBER OF PARTICLES BEING ABOUT 0.5 MICRON OR LESS IN SIZE AND LESS THAN 15% OF THE NUMBER OF PARTICLES BEING GREATER THAN ABOUT 0.5 MICRON IN SIZE. THE COMPOSITIONS PROVIDE MOLDED ARTICLES WITH SUBSTANTIAL AND UNEXPECTED IMPROVEMENTS IN IMPACT RESISTANCE-ESPECIALLY AT LOW TEMPERATURES-AND ENHANCED SURFACE APPEARANCE.
