Abstract
In accordance with certain of its aspects, this invention relates to stabilizing compositions; to stabilized polymers; and to the process for preparing a novel halogen-containing polymer stabilized against the deteriorative effect of heat which comprises adding to a halogen-containing resin a stabilizing amount of: a first stabilizer having the formula RSn(SR').sub.3 wherein R is selected from the group consisting of methyl, butyl and octyl radicals and R' is a residue of a carboxylic acid ester derived from acetic or propionic acid and a monohydric alcohol containing between 8 and 12 carbon atoms or a dodecyl hydrocarbon radical; and a second stabilizer of the formula R".sub.2 Sn.dbd.S wherein R" represents a monovalent hydrocarbon radical selected from the group consisting of methyl and butyl radicals.
