Abstract:
1. A polymeric composition comprising: (a) a polymer component comprising a polymer normally susceptible to heat-induced deterioration, (b) degradation products of a blocked mercaptan present during processing of said polymeric composition at an elevated temperature, wherein said degradation products comprise a free mercaptan, and wherein said blocked mercaptan has the structure: wherein: a is 0 or 1, m and n are 0 or 1; y=1 to 4; when y=1, z is 1 to 4; and when y is more than 1, z is 1; R alkylcarbonyloxy(polyalkoxy)carbonylalkyl radical having from 1 to 22 carbon atoms; R X is aryl, haloaryl, alkaryl, hydroxyaryl, dihydroxyaryl, aralkyl, alkoxyaryl, arylcycloalkyl, or a heteroatom; with the option that, when a is 1 and m is 0, one of the R with the further option that, when m is 1, R with the proviso that, when R (c) a mono-organotin compound or mixture of mono-organotin compounds; and (d) optionally, a diorganotin compound or mixture of diorganotin compounds.
