Some new methods of chemical modification of poly((

Some new methods of chemical modification of poly((.+-.)-epichlorohydrin). Bortel, Edgar; Lamot, Ryszard (Inst. Chem., Jagiellonian Univ., Krakow, Pol.). Rocz. Chem., 50(10), 1765-70 (English) 1976. CODEN: ROCHAC. DOCUMENT TYPE: Journal CA Section: 38 (Elastomers, Including Natural Rubber) Poly[(.+-.)-epichlorohydrin] (I) [61630-87-3] of mol. wt. 7.1 .times. 105 (prepd. by polymn. of (.+-.)-epichlorohydrin in ether in presence of Et3Al) was modified by treatment with diethanolamine (II) [111-42-2] and triethanolamine (III) [102-71-6], iminodiacetic acid (IV) [142-73-4], and KOH in dioxane [123-91-1], HCONMe2 [68-12-2], and HCONEt2 [617-84-5], to obtain new polyelectrolytes. The degree of degrdn. of I depended on the nature of the nucleophilic reagent used and decreased in the order: KOH > III > IV > II. Among solvents used dioxane had the largest effect on degrdn.; HCONEt2, the least. No relation was found between degree of substitution and degree of degrdn.

Dyeing and printing of blends of acetate fibers

Dyeing and printing of blends of acetate fibers. Abe, Kazukuni; Sakurai, Tatsuo (Asahi Chemical Industry Co., Ltd., Japan).There are some reagents like 56576-72-8 is used in this study. Japan. Kokai JP 52059782 17 May 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: D06P003-87. APPLICATION: JP 75-135659 13 Nov 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Blends of acetate fibers were dyed with Suminol Milling Yellow MR (I) or a similar dye with good fastness by using 2,2'-(ethylenedithio)diethanol (II) [5244-34-8] or a similar compd. as a swelling agent and N,N-diethylformamide (III) [617-84-5] or a similar compd. as a dyeing accelerator. Thus, a acetate-wool fabric was dyed with 1 L aq. soln. contg. I 20, II 40, III 30, ammonium sulfate 10, thiodiethylene glycol 30, and a paste 10 g. .
