    Abstract: Use of amines (I) is claimed as bleaching enhancers for textile detergents. (I) have pKa > (A-1) (preferably pKa > (A+0.5)). A = pH of the textile washing composition which contains 1 wt.% wash liquor. especially at least 0.5 above the pH. Also claimed are bleaching agents and textile detergents containing (A) 0.5-40 wt.% peroxide and/or percarboxylic acid bleach; (B) 0-20 wt.% bleach activator; and (C) 0.1-1 (especially 0.25-0.45) wt.% of a sec. amine of formula R NH-R (II), (III) or (IV). R = 6-14C hydrocarbyl or 6-14C hydroxyhydrocarbyl; and R = 1-5C hydrocarbyl, preferably Me; p, q = 0-4; X = 1-8C alkylene (optionally interrupted by O, S, O-C(O)-, NR or -NR-C(O)-) or 2-8C alkenylene; R = 1-8C alkyl; Y = as for X or bond, O, S, -O-C(O)-, or -NR-C(O)-; or when p+q

    Abstract: A low viscosity mixt. contains (i) 40-97.5 wt.% of amphiphilic nonionic graft polymer contg.(a) at least 20 wt.% of polyalkylene oxide units or polyvinylpyrrolidone units as the hydrophilic part of the molecule and (b) at least 40% of vinyl ester and/or (meth)acrylic ester units as the hydrophobic part of the molecule, (ii) 2.5-60% of polyalkylene glycol,alkoxylated alcohol, alkylphenol or amine, or 2-10C cpd. with 1-4 OH gps., when Mn of the polymers is not above 2500, as viscosity reducer, and (iii) 0-40% of homogenising or phase stabilising additive comprising (1) water, (2) an 8-25C mono- or di-basic acid, fatty alcohol sulph(on)ate, alkylbenzene sulphonate, sulphonation and/or sulphation prod. of 8-22C alkoxylated alcohol or alkylphenol, alkyl(poly)glucoside with 1-20C in the alkyl gp., mono-, oligo- or poly-saccharide or derivs. obtd. by oxidn. or redn., or (c) mixts. of (1) and (2) in ratio by wt. of 100:1-20:80.

    Abstract: The invention concerns powdery porous polymers which contain N-vinylimidazol units and are obtained by the radically initiated polymerization in the manner of precipitation polymerization of: a) between 5 and 100 wt.% of at least one N-vinylimidazol of formula (I) in which R , R and R are identical or different and stand for H, C1 - C4 alkyl, monomers of formula (II), in which R and R are identical or different and stand for H, C1 - C4 alkyl or form with one another a ring comprising between 3 and 5 methylene groups, N-vinyloxazolidone, N-vinyltriazol, 4-vinylpyridine-N-oxide or a mixture of said monomers; b) between 0 and 95 wt.% of other copolymerizable monoethylenically unsaturated monomers; and c) between 0 and 50 wt.% of at least one monomer with at least two ethylenically unsaturated non-conjugated double bonds; in an aqueous solution which contains between 0.5 and 30 wt.% of at least one electrolyte and, relative to the monomers used, between 0.5 and 80 wt.% of at least one surfactant. The invention further concerns processes for their preparation and the use of the resultant powdery porous polymers containing N-vinylimidazol units as washing agent additives in order to inhibit dye-transfer during the washing process.

    Abstract: The invention relates to a process for preparing copolymers from vinyl esters and monoethylenically unsaturated carboxylic acids by the radical copolymerisation of: (a) 20 to 80 mol % vinyl esters of aliphatic monocarboxylic acids having at least two carbon atoms, (b) 80 to 20 mol % monoethylenically unsaturated carboxylic acids and, optionally, (c) 0 to 30 mol % of other monoethylenically unsaturated monomers which can be copolymerised, and/or (d) 0 to 10 mol % monomers containing at least two ethylenically unsaturated non-conjugated double bonds in the molecule, in the presence of at least one sulphur, phosphorus and/or nitrogen compound having a reducing effect and of 0.05 to 30 wt %, relative to the monomers, of at least one surfactant in an aqueous medium and in the presence of initiators and, optionally, regulators. The invention further relates to the use of the copolymers or the copolymers comprising vinyl alcohol units obtained therefrom by hydrolysis and/or oxidation, as additives for washing and cleaning agents.
