摘要： The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method.

摘要： The invention relates to sulfonic acid group-containing copolymers, which also contain the following constituents that are incorporated by polymerization in a statistical or block-by-block manner: (a) 30 to 95 mol % of a least one monoethylenically unsaturated carboxylic acid, one monoethylenically unsaturated carboxylic acid ester, or one water-soluble salt of a monoethylenically unsaturated carboxylic acid; (b) 3 to 35 mol % of at least one sulfonic acid group-containing monomer of formula (I), in which the variables have the following meanings: R represents hydrogen or methyl; X represents a chemical bond or -C00-R -; R represents unbranched or branched C1-C4 alkylene; M represents hydrogen, alkali metal or ammonium, and; (c) 2 to 35 mol % of at least one non-ionic monomer of formula (II), in which the variables have the following meanings: R represents hydrogen or methyl; R represents a chemical bond or unbranched or branched C1-C6 alkylene; R represents identical or different unbranched or branched C2-C4 alkylene groups; R represents unbranched or branched C1-C6 alkyl, C5-C8 cycloalkyl or aryl, and; n represents 3 to 50. These copolymers are used as an additive in detergents and cleansers.

摘要： The invention relates to a lignocellulosic material which contains a cross-linkable nitrogen compound which is technically a formaldehyde condensate, in cross-linked form in an amount (N) of at least 1 wt.- %, which is calculated as nitrogen and in relation to the total weight of the lignocellulosic material. The quotient (FA/N) of formaldehyde emissions (FA), determined by means of the bottle method according to EN 717 part 3, and the amount of the nitrogen compound (N) has a value of a maximum 5,0 x 10-3. The invention also relates to a method for the production thereof.
