Title
(EN) TRANSPARENT IMPACT RESISTANT THERMOPLASTIC RESIN COMPOSITION
Abstract
(EN) AN AROMATIC VINYL RESIN COMPOSITION COMPRISING (A) 5 TO 40 % BY WEIGHT OF A GRAFT COPOLYMER OBTAINED BY POLYMERIZING 15 TO 60 PARTS BY WEIGHT OF (A4) A VINYL MONOMER IN THE PRESENCE OF 85 TO 40 PARTS BY WEIGHT OF RUBBER PARTICLES (TOTAL OF VINYL MONOMER AND RUBBER BEING 100 PARTS BY WEIGHT) HAVING AN AVERAGE PARTICLE SIZE OF 3,500 TO 20,000 ANGSTROMS OBTAINED BY ADDING, TO A LATEX OF A RUBBER HAVING AN AVERAGE PARTICLE SIZE OF 500 TO 3,000 ANGSTROMS AND COMPRISING (A1) 50 TO 100 % BY WEIGHT OF A DIENE MONOMER, (A2) 50 TO 0 % BY WEIGHT OF A VINYL MONOMER AND (A3) 0 TO 3 % BY WEIGHT OF A CROSSLINKING MONOMER, 0.1 TO 15 PARTS BY WEIGHT OF AN ACID GROUP-CONTAINING COPOLYMER PER 100 PARTS BY WEIGHT OF THE RUBBER TO AGGLOMERATE THE RUBBER PARTICLES TO ENHANCE THE PARTICLE SIZE THEREOF, AND (B) 95 TO 60 % BY WEIGHT OF AN AROMATIC VINYL RESIN COMPRISING (B1) 40 TO 100 % BY WEIGHT OF AN AROMATIC VINYL MONOMER, (B2) 60 TO 0 % BY WEIGHT OF A METHACRYLIC ESTER AND (B3) 0 TO 20 % BY WEIGHT OF OTHER VINYL MONOMER. THE COMPOSITION PROVIDES MOLDED ARTICLES HAVING AN IMPROVED IMPACT RESISTANCE WITHOUT IMPAIRING PROPERTIES OF THE AROMATIC VINYL RESIN SUCH AS HEAT RESISTANCE AND TRANSPARENCY.
