Abstract
Vulcanized rubber contains as antiozonant a thiourea having one or more alkyl, alkenyl, aralkyl or alicyclic substituents in the molecule. The proportion of such antiozonant may be 0,1-5% of the rubber. Rubbers referred to are natural rubber and copolymers of an aliphatic conjugated diolefine, e.g. butadiene, with styrene, acrylonitrile, methyl vinyl ketone and methyl isopropenyl ketone. Examples are of testing vulcanizates of such rubbers containing di-n-butyl, di-n-hexyl, dibenzyl, diethyl, di-n-octyl, di-n-dodecyl, di-n-hexadecyl, di-n-octadecyl, di-n-octadecenyl, N-methyl-N1-dodecyl, tributyl and N,N-petnamethylene-N1-benzyl, and tetrabutyl thioureas and diethyl and dibenzyl thioureas in a polyethylene amine carrier of composition R.N[(C2H4O)nH]2, R being the oleyl group. Specification 887,173 is referred to.
