Patent ID: 6927247

Claim:
A polymer composition comprising: a chlorine-containing or bromine-containing polymer; and a heat stabilizer component consisting of a) an organic thiol compound having the formula: wherein E is 1 to about 5, wherein R 12 is a straight chain or branched alkylene having from 1 to about 15 carbon atoms, wherein R 13 is i) a linear, cyclo-, or branched alkyl or alkylene group, having from 1 to about 25 carbon atoms, or ii) an aralkyl or aralkylene group having from 7 to about 25 carbon atoms, or said i) or ii) having at least one heteroatom, and wherein D is 1 to about 10; and optionally b) a non-metal-containing heat stabilizer free of a terpene compound, wherein said organic thiol compound is present in an amount from about 1 to about 100 parts by weight per 100 parts by weight of said polymer.
