Kokai Tokkyo Koho JP 09003390 A2 7 Jan 1997 Heisei, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C09D129-04. ICS: C08F216-06; C08F220-54. APPLICATION: JP 1995-179388 21 Jun 1995. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The coatings contain poly(vinyl alc.)-type resins copolymg. 0.1-20 mol.% ethylenic unsatd. dicarboxylic monoamides C(O)NR1CR2R3R4 (R1 = H, alkyl, aryl; R2-4 = H, alkyl, aryl; total C no. of R2-4 34; only 1 of R2-4 can be H). Thus, adding (a) MeOH soln. of 27.Several substances with their cas registry numbers 184172-28-9 and 543-82-8 may be metioned in this study.2 parts N-tert-octylmaleic monoamide prepd. from maleic anhydride and tert-octylamine and (b) AIBN MeOH soln. simultaneously to a system contg. 1000 parts vinyl acetate (I) and MeOH, blowing MeOH steam to remove unreacted I, dilg. with MeOH, and neutralizing and sapong. with MeOH gave a resin with sapon. degree 90 mol.%, B-type viscosity (4% soln., 20°) 27.9 cP, and d.p. 1700. A coating comprising the resin 100, glycerin 20, hydroxyethyl cellulose 20, EtOH 50, and H2O 550 parts was bar-coated to a corrugated cardboard and left at 20° and 65% RH to show tack-free property. .

CLASS: ICM: C11D003-37. APPLICATION: DE 85-3528460 8 Aug 1985. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) The title polymers are used in detergents as graying inhibitors and detergency improvers. 543-82-8 and 26677-99-6 are also in the experiment. A copolymer (mol. wt. 45,000) was prepd. from 675 parts maleic anhydride and 825 parts acrylic acid, and 200 parts suspension (49.9% solids) of the copolymer was treated at 70% with 51 parts tridecylamine and 128 parts H2O to prep. a detergent additive. .
