Abstract
Butyl rubber is vulcanized by heating it with a dimethylol phenol and chlorosulphonated polythene in the presence of zinc oxide or of a zinc salt of a fatty acid. The Butyl rubber may be derived from isobutylene or ethyl methyl ethylene and butadiene, isoprene, piperylene, 1,2-, 1,3-, 1,4-, or 2,3-dimethyl butadiene or 1-ethyl butadiene. The dimethylol phenol may be resinous or not, and specified are 2,6-di-methylol 4-hydrocarbon phenols where the hydrocarbon is methyl, tertiary-butyl, octyl, tertiary-octyl, dodecyl, phenyl, benzyl, alpha, alpha-dimethyl-benzyl and cyclohexyl. Specified zinc salts are the laurate and stearate. Preferred amounts of phenol are about 4 to 15 parts, of chlorosulphonated polythene about 2 to 10 parts, and of zinc oxide (or its salt equivalent) 1 to 5 parts, all per 100 parts of Butyl, while preferred temperatures are 320-370 DEG F. The rubber may be compounded with reinforcing material, e.g. carbon black, and used for curing bags or inner tubes. Specification 718,768 is referred to.
