Abstract: Water-soluble polymers having K values of from 5 to 100 (determined on the Na salt of the polymers according to H. Fikentscher in aqueous solution at 25.degree.C, a pH of 7 and a concentration of 1% by weight of the Na salt of the polymer) are prepared by polymerizing a monomer mixture of (a) monoethylenically unsaturated C3-C5-monocarboxylic acids and (b) more than 20-100 mol % of monomers which have two or more ethylenically unsaturated double bonds linked via one or more ester or amide functions and which contain one or more -CO-OX groups, where X is one hydrogen equivalent, one alkali metal equivalent or one alkaline earth metal equivalent or an ammonium group, in aqueous solution in the presence of a polymerization initiator, and the polymers are used in amounts of from 0.5 to 25% by weight in detergents and cleaners.

Abstract: A process for preparing polyacetals by copolymerization of glyoxylic esters with other copolymerizable monomers in the presence of anionic or cationic polymerization initiators, with or without the introduction of stable end groups and with or without hydrolysis of the copolymerized units of glyoxylic ester present in the copolymer comprises using as monomers cyclic formals derived from diols, homopolymers of formaldehyde, trioxepane or mixtures thereof, although up to 50 % by weight of this group of monomers may be replaced by other customary copolymerizable monomers, and the poly(acetal-carboxylate)s thus obtainable are useful as additives in reduced-phosphate and phosphate-free detergents and cleaners, as water treatment agents and as dispersants for finely divided substances.
