PCT No. PCT/US92/09091 Sec. 371 Date Dec. 18, 1992 Sec. 102(e) Date Dec. 18, 1992 PCT Filed Oct. 27, 1992 PCT Pub. No. WO93/13168 PCT Pub. Date Jul. 8, 1993.A thermoformable chemical resistant polymer blend, useful in the preparation of refrigerator and freezer liners comprising: A) from 45 to 70 parts by weight impact modified monovinylidene aromatic polymer, comprising from 1 to 25 weight percent of a rubber and 75 to 99 weight percent of a monovinylidene aromatic polymer matrix having a molecular weight (Mw) from 50,000 to 400,000, said weight percents being based on the total weight of said impact modified, vinylaromatic polymer; B) from 15 to 40 parts by weight of an olefin polymer, selected from the group consisting of homopolymers of ethylene or propylene and copolymers of ethylene with one or more C4-8 alpha -olefins; and C) from 5 to 25 parts by weight of a compatibilizing polymer, adapted to increase interfacial adhesion between components A) and B), components A) and B) or components A), B) and C) existing in said blend as co-continuous phases, and the sum of A),B) and C) being 100 parts.
