Resin composition and resistance to flon resistance refrigerator exterior moldings

摘要

PURPOSE: To obtain a resin compsn. with excellent impact resistance, rigidity, luster and surface hardness and resistance to a substd. chlorfluorohydrocarbon by compounding a specified rubber-contg. styrene resin and two kinds of acrylic (co)polymers with different glass transition temp. ;CONSTITUTION: 15-65wt.% ingredient A, 1-25wt.% ingredient B and 20-70wt.% ingredient C described below are compounded. The ingredient A is a rubber- contg. styrene resin consistinf of a continuous phase of a copolymer resin wherein a styrene monomer component and a nitrile monomer component are essential ingredients and a rubber ingredient as dispersed particles. In addition, the content of the nitrile monomer component in the continuous phase is at least 30wt.% and at least a part of the rubber is graft-bonded with the above described monomer components in the rubber ingredient in the dispersed particles. The ingredient B is a (co)polymer of acrylate and/or (meth)acrylate with a glass transition temp. of at most 20°C. The ingredient C is a (co)polymer of (meth)acrylate being the same as the ingredient B and with a glass transition temp. of higher than 20°C.;COPYRIGHT: (C)1995,JPO
