ABSTRACT:
An improved process for preparing chlorobutyl rubber compositions employs, as curing agent, para-tert. butyl phenol disulfide having a sulfur content in excess of about 27 wt% and a softening point not less than 80.degree.C. Para-tert. butyl phenol disulfide is a solid substance which, unlike other commercially employed alkyl phenol sulfides, is a non-tacky brittle solid which does not deteriorate as by coalescing under normal storage conditions.
