PURPOSE:To obtain the title composition mixable into a light color, having excellent heat resistance and freeze resistance, slightly causing aggregation and bloom, by blending chlorosulfonated polyethylene with a heat-resistant plasticizer, freeze-resistant plasticizer and a specific antioxidant composition. CONSTITUTION:(A) Chlorosulfonated polyethylene is blended with (B) 1-50% heat resistant plasticizer (e.g., trioctyl trimellitate and/or diisodecyl adipate), (C) 1-50% freeze-resistant plasticizer (e.g., dioctyl acetate, di-2-ethylhexyl adipate or trioctyl phosphate) in the weight ratio of the component B and C of 7:3-3:7 and further (D) 0.5-3% nickel dibutyl-dithiocarbamate, 0.5-3% tris(nonylic acid phenyl) phosphite, 0.5-3% tris(3,5-di-t-butyl-4-hydroxybenzoyl) isocyanurate, 0.5-3% dilauryl thiodipropionate and 0.5-3% hindered bisphenol to give a composition. |
