CHLOROFLUOROCARBON-RESISTANT RESIN COMPOSITION AND INNER BOX OF REFRIGERATOR MADE FROM THE COMPOSITION

WIPO Patent Application WO/1997/025376

A1

A chlorofluorocarbon-resistant resin composition comprising a cluster-like agglomerate graft polymer (Y) which is formed by the agglomeration of a small-particle-size graft copolymer (y) prepared by polymerizing 60 to 20 wt.% of a monomer mixture comprising 30 to 45 wt.% of a vinyl cyanide compound and 70 to 55 wt.% of an aromatic vinyl compound in the presence of 40 to 80 wt.% of a rubbery polymer having a weight-mean particle diameter of 0.05 to 0.2 'mu'm and having a graft ratio of 10 to 40 wt.% and has a weight-mean particle diameter of 0.8 to 2.0 'mu'm and a copolymer (Z) prepared by polymerizing 35 to 45 wt.% of a vinyl cyanide compound with 65 to 55 wt.% of an aromatic vinyl compound and having an intrinsic viscosity of 0.6 to 0.9, with the content of the rubbery polymer being 15 to 25 wt.%. This composition is superior to the prior-art resin compositions in chlorofluorocarbon resistance.
