Polybutene composition containing halocarbonyl additives: Polybutene composition containing halocarbonyl additives. Puskas, Imre; Cengel, John A. (Standard Oil Co. (Indiana), USA). U.S. US 4028264 7 Jun 1977, 5 pp. Division of U.S. 3,953,475. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07D307-36. NCL: 252182000. APPLICATION: US 73-358958 10 May 1973. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 51 Viscous polybutene (I) [9003-29-6] having no.-av. mol. wt. 300-3000 had improved reactivity toward maleic anhydride (II) [108-31-6] when treated in the presence of 5-200 ppm .alpha.-bromo dialkyl ketone or acetal. The additive also suppressed the formation of tarry materials during the addn. reaction. Thus, a mixt. of 10 g I, 1.1 g II, and 73 ppm 1,4-dibromo-2,3-butanedione [6305-43-7] was heated 6 h at 249.degree. in N to yield 75.5% I-II adduct contg. 0.2% tar, compared to a 63.3% yield of the adduct contg. 1.3% tar for the reaction without the additive. Also used as additives were.alpha.-bromoacetonaphthone [59799-20-1] and .alpha.-bromoacetophenone [70-11-1].

Covulcanizing chlorinated low unsaturation rubbers with high unsaturation rubber: Covulcanizing chlorinated low unsaturation rubbers with high unsaturation rubber. Newman, Neil F. (Exxon Research and Engineering Co., USA). U.S. US 4025695 24 May 1977, 6 pp. Division of U.S. 3,985,832. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08L007-00. NCL: 428492000. APPLICATION: US 75-537857 2 Jan 1975. DOCUMENT TYPE: Patent CA Section: 38 (Elastomers, Including Natural Rubber) The compatibility of butyl rubber with a highly unsatd. rubber is improved by addn. of Br- or I-contg. compds. Thus, a chlorobutyl rubber compn. was combined with .alpha.-bromoacetophenone [70-11-1] (0.5, 0.25, and 0.125 mol Br/mol Cl), cured and adhered to a natural rubber strip. The chlorobutyl rubber exhibited ASTM D413-38 strip adhesion (in lb/in.) to the natural rubber 165 T, 125 T, and 80 T, (T = stock tearing), resp., at 24.degree. and 75 T, 80 T, and 9 I (I = interfacial sepn.), resp., at 121.degree..
