Abstract

A halogen-containing thermoplastic resin composition comprising a halogen-containing thermoplastic resin (A), a metallic soap (B) and an ash- and alkali metal-lean ethylene-vinyl acetate copolymer hydrolysate (C) having an ethylene content of 20 to 75 mole percent, a degree of saponification not less than 50 mole percent, an ash content not exceeding 300 ppm and an alkali metal content not exceeding 200 ppm, the proportions of (B) and (C) based on 100 parts of weight by (A) being 0.1 to 5 parts by weight and 0.1 to 5 parts by weight, respectively. The composition may further include, in addition to (A), (B) and (C) mentioned above, at least one compound (D) selected from the group consisting of .beta.-diketone compounds, organic phosphorous esters and aminocarboxylic acid compounds, the proportion of (D) based on 100 parts by weight of (A) being 0.05 to 5 parts by weight, and/or at least one compound (E) selected from the group consisting of phenol derivatives and epoxy compounds, the proportion of (E) based on 100 parts by weight of (A) being 0.01 to 5 parts by weight.
