Abstract

Polymers of alpha-olefins or copolymers of alpha-olefins with each other and/or with ethylene are vulcanized by mixing the polymer with an alkyl, an alkylaryl, or acyl peroxide, or a perester, and an activator and heating the mix at a temperature of from 130 DEG to 180 DEG C. The activator may be carbon black, sulphur, selenium, or tellurium, or mixtures thereof, p-benzoquinone, o,o1-di-benzoyl-p-quinondioxime, or p-nitroso-phenol. The polymer may be polypropylene, polybutene, or a copolymer containing up to 80% ethylene, and the remainder consisting of propylene, butene, or mixtures. The vulcanizable mix may also contain a filler which may be carbon black. Specified peroxy compounds are benzoyl and phthalyl peroxides, tert. butyl-diperbenzoate, -dipersuccinate, -dipermaleate, -diperphthalate, 2,21-((t)-butyl peroxy) butane, (t)-amyl-, (t)-butyl-, and cumyl-peroxide. The heat-treatment of the mix is generally effected in a vulcanizing press. Specifications 828,791, 856,733, 856,736, 856,737 and 885,970 are referred to. Reference has been directed by the Comptroller to Specification 850,455.
