    Abstract: The invention concerns polyacetal-block-containing polymers obtained by polymerizing, in the presence of initiators, carboxylic acid esters containing aldehyde groups and by reacting the polymers with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids and optionally hydrolysing the ester groups thus incorporated in the polymer. The invention also concerns a method of producing polymers containing polyacetal blocks by polymerizing carboxylic acid esters containing aldehyde groups in the presence of initiators and reacting the polyacetals containing terminal hydroxy groups thus obtained with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids, plus the use of the polymers thus obtained as additives in phosphate-free and phosphate-reduced washing and cleaning agents, as scale inhibitors and as dispersants for pigments.

    Abstract: Copolymer contains (a) at least 12 wt. % of a mono-or poly-unsatd. carboxylic acid anhydride and (b) a ketone deriv. radically polymerising by ring opening. Pref. (a) the components are anhydrides of mono- or di-carboxylic acids, esp. anhydrides of methacrylic, maleic and/or itaconic acids. (b) the components are ketene monothio or aminoacetals or derivs. of formula (I), X = O, S or NR1, R = 2-7C alkylene opt. by C1 or 1-4C alkoxy, R1-1-8C alkyl. Claimed ketene derivs. are 2-methylenedioxepan-1, 3;2-methylene-dioxolan-1, 3;, N-R1-2-methylene-1, 3-hexahydrooxazepin, N-R1-2-methylene-oxazolidin-1,3-2-methyleneoxathiepan-1,3 or 2-methyleneoxathiolan-1, 3. The copolymer contains (a) 97.5-25% of an anhydride of a monoethylenically unsatd. mono or di-carboxylic acid, (b) 2.5-75% of the ketene deriv. and (c) 0-20% of another, copolymerisable, monomer and has K value of 8-100 as the water-sol. salts. USE - Copolymers are used, as water-sol. salts as dispersants and as soil-dispersants in washing compsns. (claimed). They are also used as supports for active materials, forming bio-erodible, slow-acting systems. The washing and cleaning compsn. are esp. low-phosphate or phosphate-free (pref).

    Abstract: Water-soluble copolymers having a K value of from 15 to 120 (determined by the method of H. Fikentscher on the sodium salt in aqueous solution at 25@C, a pH of 7 and a polymer concentration of the Na salt of 1 % by weight) which, in polymerised form, contain a) from 99.5 to 80 mol % of at least one monoethylenically unsaturated C3- to C6-monocarboxylic acid, b) from 0.5 to 20 mol % of a comonomer containing at least two ethylenically unsaturated, non-conjugated double bonds and at least one -CO-OX group and/or a salt thereof with an alkali metal, ammonium or alkaline earth metal base, the preparation of the water-soluble copolymers by copolymerisation of the monomers a) and b) in aqueous solution, and the use of the copolymers for coating seed.
