Abstract: O.Z.0050/41782 Polymers which contain as essential monomer at least 5% by weight of N-(alkyloxy-polyalkoxymethyl) carboxamides of monoethylenically unsaturated C3-C8-carboxylic acids as copolymerized units are used as additives in low-phosphate and phosphate-free detergents in amounts which increase their primary and secondary detergency.

Abstract: Petroleum distillates with improved properties contain minor amts. of a conventional ethylene-based flow improver (I) and a copolymer (II) comprising 10-95 mol.% of one or more 1-26C alkyl (meth)acrylates and 5-90 mol.% of one or more ethylenically unsatd. dicarboxylic acids or anhydrides, post-reacted with one or more primary or sec. amines to form the corresp. monoamide or amide/ammonium salt. (I):(II) wt. ratio is 40-95:60-5. - Pref. (I) is a copolymer of ethylene with vinyl acetate, vinyl propionate or ethylhexyl acrylate. (II) is a copolymer of 40-95% lauryl acrylate or 8-18C alkyl acrylate and 5-60% maleic anhydride, post-reacted with di(hydrogenated tallow) amine (DHTA), behenylamine or n-octadecylamine. (II) is opt. grafted onto (I). The distillates contain 50-5,000 ppm (I)+(II).

Abstract: Water-soluble copolymers containing copolymerized vinylamine units are prepared by copolymerizing a) from 95 to 10 mol% of N-vinylform-amide and b) from 5 to 90 mol% of an ethylenically unsaturated monomer from the group consisting of vinyl acetate, vinyl propionate, C1-C4-alkyl vinyl ethers, the esters, nitriles and amides of acrylic acid and methacrylic acid and N-vinylpyrrolidone, and then eliminating from 30 to 100 mol% of the formyl groups from the copolymer. Preferred copolymers are copolymers of N-vinyl-formamide and vinyl acetate, in which from 30 to 100 mol% of the monomer units are hydrolyzed. The copolymers are used in papermaking to increase the dry strength and wet strength of the paper.
