ORGANIC SULFIDE ANTIOXIDANTS Organic sulfide antioxidants useful for stabilizing polyolefins against oxidative and thermal degradation during processing and use represented by Formula I: (I) wherein n is an integer of 2 to 15; R is an integer group of 2 to 30 carbons, or a cycloalkyl group of 5 to 20 carbons, R is a substituted or unsubstituted alkyl group of 2 to 30 carbons, a substituted or unsubstituted cycloalkyl group of 5 to 20 carbons, a substituted or unsubstituted alkyl group of 2 to 30 carbons where any of up to 6 carbon atoms are replaced with an O or S heteroatom, a substituted or unsubstituted cycloalkyl group of 5 to 20 carbons where any of up to 6 carbon atoms are replaced with an O or S heteroatom, with the proviso that the heteroatoms must be separated from each other and from the portion of the compound to which the R group is bonded by at least one carbon atom, the substituents for R being -OH, -SR4 or -OR4, wherein R4 is an alkyl group of 1 to 3 0 carbons or a cycloalkyl group of 5 to 20 carbons; R1 and R2 are independently H or an alkyl group of 1 to 4 carbons; and R3 is an alkyl group of 1 to 24 carbons or a cycloalkyl group of 5 to 20 carbons.
