Softening agents for synthetic fibers. Hibino, Seiji; Nishimura, Yasuo; Nakamura, Tetsuo (Takemoto Oil and Fat Co., Ltd., Japan). Japan. Kokai JP 52081197 7 Jul 1977 Showa, 9 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: D06M013-50. APPLICATION: JP 75-155852 27 Dec 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Wash-resistant acrylic or polyester fibers, with reduced friction, were prepd. by coating the fibers with mixts. contg. an aminosiloxane (I), an epoxysiloxane (II), and an aminoalkoxysilane and heat-treating the fibers. Thus, acrylic fibers were spray coated (1% as Si) with a mixt. of a 35% emulsion of I (contg. 2% amino groups) 5.7, a 20% emulsion of II (contg. 5% epoxy groups) 4, and [3-[N-(2-aminoethyl)amino]propyl]dimethoxymethylsilane [3069-29-2] 1.2, and H2O 89.1 g, dried, and heat-treated 20 min at 110° to give fibers with frictional coeff. 0.22 (static) and 0.19 (dynamic), compared with 0.26 and 0.22, resp., for fibers finished with a biguanide cationic softener.

Crosslinking of brominated butyl rubber with silane coupling agents. 2. Studies on cross-linking of halogenated butyl rubber with silane-coupling agents.

ISSN: 0029-022X. DOCUMENT TYPE: Journal CA Section: 39 (Synthetic Elastomers and Natural Rubber) Polysar Bromobutyl X2 was crosslinked with g-aminopropyltriethoxysilane [919-30-2], N-(b-aminoethyl)-g-aminopropyltrimethoxysilane [1760-24-3], g-ureidopropyltriethoxysilane [23779-32-0] N-b-(aminoethyl)-g-aminopropyldimethoxymethyl silane [3069-29-2], and g-mercaptopropyltrimethoxysilane [4420-74-0]. The kind of crosslinking agents had a large effect on crosslinking but the kind of catalysts did not. The catalysts examd. were dibutyltin dilaurate [77-58-7], dioctyltin dilaurate [3648-18-8], and dibutyltin diacetate [1067-33-0]. Crosslinking proceeded sufficiently at 50° and relative humidity 50%.
