    Abstract: The invention relates to polymers made out of a poly(meth)acrylic acid main chain, in which, in relation to the main chain, 0 to 30 wt. % of the (meth)acrylic acid basic units can be replaced by maleic acid (anhydride) basic units, fumaric acid basic modules or mixtures thereof; and 0 to 10 wt. % of the (meth)acrylic acid basic units can be replaced by other copolymerisable, ethylenic basic units. The polymers are also made of side chains in the form of C1-30-alkylpoly-C2-4-alkylglycols which are bound to t he main chain by means of ester groups and which have an average molecular weig ht of 250 to 10,000. The main chain and side chains make up 1 to 19 wt. % and 8 1 to 99 wt. % of the polymer respectively. The ratio and the average molecular weight of the side chains are chosen in such a way that the polymer contains free carboxyl groups. Said polymers are used as controllable dispersing agen ts for detergents or constituents thereof.

    Abstract: Paper, board and cardboard are produced by a process in which a paper stock is drained in the presence of condensates of basic amino acids with sheet formation. In particular, homo- and cocondensates of lysine and the crosslinked condensates obtainable therefrom by reaction with crosslinking agents are used in amounts of from 0.01 to 5% by weight, based on dry paper stock, as a means of increasing the dry and wet strength and the absorptivity of paper, for fixing anionic dyes and interfering substances in the paper, for increasing the drainage rate and the retention as well as the efficiency of synthetic anionic and cationic retention aids in the production of paper, board and cardboard by draining a paper stock with sheet formation.

    Abstract: The invention relates to the use of grafted polymers as greying inhibitors during the washing and aftertreatment of textile goods. Said polymers are obtained by polymerising A) 10 to 95 wt. % of grafted monomers containing, in relation to A), a) 1 to 99 wt. % of at least one vinyl ester, b) 1 to 99 wt. % of at least one N-vinyl lactam, c) 0 to 90 wt. % of at least one other monoethylenically unsaturated monomer which can be copolymerised with monomers a) and b), and d) 0 to 5 wt. % of at least one monomer having at least two ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of A) 5 to 90 wt. % of at least one polymer B), chosen from polyalkylene oxides containing at least 3 units of a C2 to C4 alkylene oxide, and polytetrahydrofuranes containing at least 3 units of tetramethyl oxide units, and the mixtures thereof.

    Abstract: The invention relates to a method of producing paper, paperboard and cardboa rd by dewatering a paper material in the presence of condensation products of basic amino acids and sheet forming. The inventive method especially uses ho mo- and co-condensation products of lysine and the cross-linked condensation products obtained therefrom by reaction with cross-linking agents in an amou nt of from 0.01 to 5 wt.- % based on the dry paper material to increase the dry and wet strength and the absorbency of paper. These materials are also used to fixate anionic dyes and interfering substances in the paper, to increase the dewatering rate and the retention and the efficacy of synthetic anionic and cationic retention agents in the production of paper, paperboard and cardboa rd by dewatering the paper material and sheet forming.
