Patent ID: 6846861

Claim:
A method for imparting a pleasant, pineapple-like fragrance to a process for stabilizing a halogen-containing polymer against thermal decomposition, said method comprising mixing the polymer with a stabilizer selected from the group consisting of (a) a stabilizer comprising (A) from 50 to 100% of an organotin mercaptide of a mercaptoalkyl carboxylate, on an equivalents basis, wherein said carboxylate is selected from the group consisting of a heptanoate and a mixture of a heptanoate with up to about 80% by weight of a second carboxylate having from 8 to 20 carbon atoms in the carboxylic moiety, and (B) from 0 to 50% of the mercaptoalkyl carboxylate of which (a)(A) is the organotin mercaptide, on an equivalents basis, and (C) from 0 to 50% of a sulfide of the organotin mercaptide of which (a)(A), on an equivalents basis; and (b) a stabilizer comprising (A) an organotin mercaptide of a mercaptoalkyl carboxylate having from 14 to 20 carbon atoms in the carboxylic moiety, and (B) from about 1% to about 50% of a mercaptoalkyl heptanoate.
