    Abstract: The invention concerns condensation products containing N,O-acetal- or carbonamide structures, the products being characterized in that they are obtained by the condensation of (a) compounds containing at least once the structural element (I) or (II) in which X=OH or NHR, R being C1 to C6 alkyl or -CH2-COOH, with (b) aldehydes, ketones or aldehydic or ketonic carboxylic acids to give acetal lactones and by subsequently splitting the acetal lactones with (c) aminocarboxylic acids, primary or secondary amines and/or polyethylenimines to give condensation products containing N,O-acetal- or carbonamide structures. The invention also concerns methods of preparing such products and their use as additives in washing and cleaning agents. The invention further concerns condensation products containing acetal lactone structures produced by reacting (a) hydroxycarboxylic acids or secondary aminoacids with polyhydroxy compounds and condensing with (b) aldehydes, ketones or aldehydic or ketonic carboxylic acids.

    Abstract: Water-soluble polymers (I) of esters of acrylic acid (II) and alkyl-polyalkylene glycols (III) are obtained by a method involving azeotropic esterification of (II) and (III) in presence of organic solvent followed by radical polymerisation of the mixture with removal of solvent by azeotropic distillation and replacement of the lost water. Water-soluble polymers (I) of esters of acrylic acid (II) and alkylpolyalkylene glycols (III), obtained by azeotropic esterification of a mixture of (II) and (III) in a mol ratio of (2-3):1 in presence of at least 85 wt% (based on III) of an organic solvent which forms an azeotrope with water, followed by radical polymerisation of the resulting mixture with azeotropic distillation to remove the solvent and with replacement of lost water by recycling or by the addition of fresh water. An Independent claim is also included for a method for the production of (I) as described above.

    Abstract: Water soluble and/or dispersible polyaspartic acid derivatives of formula (I) or their (poly)carboxylic acid salts or quat. derivatives are claimed. In (I), (x1 + x2) = 30-99.9; (y1 + y2) = 0.1-70; z = 0-20; A = at least one prim., sec. or tert. 2-6C alkyl amine, optionally with 1-3 substituents chosen from OH or alkoxy on the alkyl groups, at least one diamine of formula (R )(R )N(CH2)mN(R )(R ) (II) (where m = 2-6; R , R = H or alkyl; R , R = alkyl or they combine with the N atom to which they are bonded to form a 5-7 membered saturated heterocyclic ring of formula (III) (where n', o' = 1-5; X' = CH2, S, O, NR = H or alkyl)) or at least one cyclic diamine of formula (III) (where n, o = 1-5; X = NR (where R = H or alkyl)); B = at least one amine of formula R Y(CH2)pN(R )(R ) (IV) (where the group R -Y-(CH2)p contains 6-24C atoms; p = 1-23; Y = CH2, O, N, CONH (in which the CO group is bonded to R ) or N-COR ; R = H or (un)saturated fatty acid hydrocarbon; R , R = H, (hydroxy)alkyl or -ÄCH2-CH2-OÜrH (where r = 1-30; R = alkyl)); C = at least one derivative of a prim. or sec. amine (A) with an amino H atom removed; and D = at least one derivative of a prim. or sec. amine (B) with an amino H atom removed, with the provision that x1 + x2 + y1 + y2+ z = 100 and at least one amine (A) or (B) contains a tert. amino group. Also claimed are: (i) the preparation of (I) by reacting polyaspartic acid or polysuccinimide with at least one amine (A) and at least one amine (B) and (ii) hair treatment products containing at least one compound (I).
