Abstract
Abstract A halogen-containing polymeric rubber composition having improved scorch resistance, said composition comprising 100 parts by weight of a halogen-containing polymeric rubber having incorporated therein, as a antiscorching agent 0.1-5.0 parts by weight of at least one compound of the formula SH-R-(X)n WHEREIN R is selected from the group consisting of the aliphatic, alicyclic and aromatic hydrocarbon radicals, X is selected from the group consisting of amino, imino and carboxyl radical, and n is a number from 1 to 2. and 0.5 to five parts per weight of an amino-containing cross-linking agent.
