Abstract
An anti-oxidant comprises an organo-tin derivative of a non heterocyclic mercapto-acid derivative containing the group <FORM:0747239/V/1> where R is a hydrocarbon. An organo-tin compound of the type RnSn [SR1(COOR11)x]4n may be used, where x is 1 or 2, n is an integer from 1 to 3, R is a univalent organic radical of the class consisting of alkyl, aryl or aralkyl, R1 is an aliphatic or an aromatic hydrocarbon radical having a valency of x + 1, and R11 is a hydrogen atom, or a univalent alkyl, aralkyl or aryl radical. The compound may be present in the amount of from 0.5 per cent to 5 per cent by weight of the rubber. Among numerous examples of the compound, dibutyl tin S, S1 bis (isooctyl mercaptoacetate) is referred to Specifications 719,733 and 719,421 are referred to.
