Abstract
A stabilizer for chlorine-containing resins of the invention consists of a polyol mixture composed of pentaerythritol and condensates thereof, wherein, with respect to the total amount of the polyol mixture, the content of pentaerythritol having a degree of condensation (n) of 1 is 0 to 10% by mass and the total content of pentaerythritol and condensates thereof having a degree of condensation (n) of 1 to 3 is 5 to 30% by mass. A chlorine-containing resin composition of the invention contains, with respect to 100 parts by mass of a chlorine-containing resin, 0.01 to 10 parts by mass of the above-mentioned stabilizer for chlorine-containing resins.
