Vulcanizable acrylate rubber compositions

Vulcanizable acrylate rubber compositions. Jablonski, Dane E. (Goodrich, B. F., Co., USA). U.S. US 4405758 A 20 Sep 1983, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08F008-34. NCL: 525329800. APPLICATION: US 82-379215 17 May 1982. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Dual cure site acrylate rubbers contg. both carboxyl and active halogen cure sites and having a good scorch/cure rate balance, and good phys. property balance in the vulcanizates, are obtained by compounding with a combination of Na stearate (I) [822-16-2] and tetramethylthiuram disulfide (II) [137-26-8] or Group IB, IIB, IVA, VA, or VIA metal salts. Thus, an acrylate rubber contg. Et acrylate 98, vinyl benzyl chloride 1.6, and methacrylic acid 0.4%, was masterbatched with a processing aid and carbon black, compounded with I 4.0 and II 0.75, tetrabutylthiuram disulfide (III) [1634-02-2] 1.25, zinc tetraethylthiuram disulfide (IV) [14324-55-1] 1.25, lead tetramethylthiuram disulfide (V) [19010-66-3] 1.5, or zinc tetramethylthiuram disulfide (VI) [137-30-4] 1.0 part, and cured. Unlike compds. contg. II, IV-contg. compds. had inferior cure activity. Of the 5 compds. tested, compds. contg. II and V had an excellent balance of phys. properties. The tensile strength of the compds. decreased in the order: V > II > VI > IV > III.

Some aspects of the fully soluble efficient vulcanization (FSEV) system

Some aspects of the fully soluble efficient vulcanization (FSEV) system. Lye, Chan Boon (Rubber Res. Inst. Malay., Kuala Lumpur, Malay.). J. Rubber Res. Inst. Malays., 24, Pt. 5, 272-82 (English) 1976. CODEN: JRRIAN. DOCUMENT TYPE: Journal CA Section: 38 (Elastomers, Including Natural Rubber) The development of the fully sol. efficient vulcanization system (FSEV), its cure characteristics, and advantages over conventional vulcanizing systems are discussed. In the FSEV system stearic acid is replaced by 2-ethylhexanoic acid [149-57-5] or its Zn soap [136-53-8], cyclohexylbenzothiazyl sulphenamide is replaced by 2-morpholinylbenzothiazyl sulphenamide [63504-14-3], and tetramethylthiuram disulfide is replaced by tetrabutylthiuram disulfide [1634-02-2]. The structural features of vulcanizate networks are examd. in relation to their phys. properties. The system is evaluated by heat aging of the vulcanizates contg. various antioxidants and by the properties of carbon black-filled vulcanizates.
