Abstract
1375759 Dehydrohalogenation of halobutyl rubber; rubber compositions EXXON RESEARCH & ENG CO 28 Feb 1972 [23 Feb 1972 (2)] 9137/72 Headings C3P and C3Q Copolymers of 85-99À5 wt. per cent of a C 4-7 isoolefin with 15-0À5 wt. per cent of a C 4-14 conjugated diolefin, said copolymers having a number average M.W. of 25,000 to 500,000 and containing conjugated diene unsaturation in the linear backbone thereof, are produced by contacting a solution of a halogenated butyl rubber with a mixture of (a) from 2 x 10 to 2 x 10 moles, per 100 grams rubber, of a soluble carboxylate of a Group Ib, IIb, IVa or VIII metal (Mendeleev); (b) 0-2 moles of a carboxylic acid per gram atom of halogen in said rubber; and (c) 0À5-2 moles, per gram atom of halogen in said rubber, of a Group Ia or IIa metal oxide, hydroxide or carboxylate. In examples, commercial chlorinated butyl rubbers are treated in xylene solution with mixtures comprising (a) zinc salts of naphthenic, neo-decanoic, neo-heptanoic, mixed neo-C 9-13 or mixed neo-C 9-10 acids; (b) the corresponding free acids; and (c) CaO, MgO or Ca(OH) 2 . Certain of the products are stated to contain ester groups. The above products are curable, e.g. with such polyfunctional curing agents as m-phenylenebis-maleimide, ethylene glycol dimethacrylate and trimethylene propane trimethacrylate; and are vulcanizable with conventional sulphurcontaining systems. They are also co-vulcanizable with other rubbers, e.g. natural rubber and SBR. Formulated compositions also contain additives selected from carbon black, processing oil and di(tertbutyl)-p-cresol.
