Abstract

Halogenated isobutene/conjugated diolefin copolymers (e.g isobutene/isoprene copolymer) are vulcanized with the aid of organic peroxides with/without sulphur. Covulcanization with saturated or unsaturated elastomers may be effected in the same manner, e.g. with ethylene/propylene copolymers or silicone rubber. In examples the peroxides used are cumyl and chlorinated t-butyl peroxides and other ingredients present are carbon black, magnesium oxide and phenyl-b -naphthylamine. The products find application in the manufacture of tyres.
