Weatherable,high impact,thermoplastic resin composition

Abstract

Abstract A THERMOPLASTIC RESIN COMPOSITION ESSENTIALLY OF (I) HIGH IMPACT-RESISTANCE RESIN (A) OBTAINED FROM GRAFT POLYMERIZING THE MIXTURE CONSISTING ESSENTIALLY OF (A) 9840% BY WEIGHT MONOMER OR MONOMER MIXTURE CONTAINING AT LEAST 70% BY WEIGHT OF MONOMER OR MONOMER MIXTURE SELECTED FROM THE GROUP CONSISTING OF VINYL AROMATIC, METHARYLIC ACID ALKYL ESTER WHEREIN THE ALKYL GROUP CONTAINS 1-3 CARBON ATOMS, AND ACRYLONITRILE AND LESS THAN 30% BY WEIGHT OF OTHER VINYL MONOMER, WHEREIN, IN SUCH MONOMER OR MONOMER MIXTURE THE SUM OF 3.5 TIMES THE PERCENT BY WEIGHT OF ACRYLONITRILE PLUS THE PERCENT BY WEIGHT OF SAID METHACRYLIC ACID ALKYL ESTER IS WITHIN THE RANGE OF 25-1500% BY WEIGHT OF THE MONOMER OR MONOMER MIXTURE, (B) FROM 2-60% BY WEIGHT RUBBERY GRAFT ACTIVATED COPOLYMER OF ETHYLENE AND VINYL ACETATE, WHEREIN THE ETHYLENE CONTENT IS FROM 60-95% WEIGHT, AND (II) HIGH IMPACT-RESISTANCE RESIN (B) OBTAINED FROM (C) GRAFT POLYMERIZING THE MIXTURE OF ABOUT MORE THAN 4% BY WEIGHT, PREFERABLY LESS THAN 70% BY WEIGHT, POLYBUTADIENE SERIES RUBBER AND ABOUT LESS THAN 96% BY WEIGHT, PREFERABLY MORE THAN 30% BY WEIGHT SAID MONOMER OR MONOMER MIXTURE (A), OR (D) BLENDING SAID POLYBUTADIENE SERIES RUBBER WITH THE RESIN OBTAINED FROM POLYMERIZING SAID MONOMER OR MONOMER MIXTURE (A) WITH THE TERMOPLASTIC RESIN COMPOSITION THUS OBTAINED, POLYBUTADIENE SERIES RUBBER SHOULD BE WITHIN THE RANGE OF 2-70% BY WEIGHT OF TOTAL RUBBER CONTENT.
