    摘要： A process for preparation of a highly chlorinated isobutylene-multiolefin copolymer, such as butyl rubber, containing more than one but not exceeding two chlorine atoms per double bond of the copolymer by chlorinating such copolymer in the presence of an aliphatic diamine derivative, such as ethylene diamine, propylene diamine, piperazine, triethylene diamine or bis-N,N-ethylene-ethylene diamine. A vulcanizable composition containing such chlorinated copolymer has has improved rate of vulcanization, covulcanizability with highly unsaturated rubber and adhesiveness.

    摘要： The invention relates to a pressure-sensitive adhesive composition which comprises a rubber component including at least 50 percent by weight of styrene-butadiene copolymers in combination with a resin component consisting of an aromatic hydrocarbon resin resulting from the polymerization of a thermally cracked petroleum fraction at temperatures in the range of -30.degree. to +60.degree. C. in the presence of Friedel-Crafts catalysts. The fraction as recovered from petroleum refining has a boiling range of 140.degree. to 220.degree. C. but is further fractionated to separate components boiling above and below about 180.degree. C. The material which is reacted has a conjugated diolefin content of 0.7 weight percent or less, and a ratio of conjugated diolefin content to total polymerizables of 3% or less. The total content of indene and its alkyl derivatives is 2 weight percent or less, and the ratio of indene content to total polymerizables is 8% or less. The fraction also contains significant amounts of vinyl toluenes boiling from 168.degree. to 171.degree. C.
