Abstract: An epichlorohydrinamine polymer has a ratio of amine units to epichlorohydrin units of from 0.8:1.2 to 1.0:1.0, dimethylaminopropylamine and benzylamine preferably being used as amine and/or ammonium units. The novel epichlorohydrinamine polymer is used, for example, for the surface treatment of semifinished leather products and textile materials.

Abstract: The present invention relates to copolymers prepared by copolymerization in at least two stages, wherein, in one stage (A) at least one (co)polymer is prepared from a monomer or a mixture of comonomers comprising (a1) from 80 to 100% by weight of at least one ethylenically unsaturated carboxylic acid, (a2) from 0 to 20% by weight of at least one C 1 -C 22 -alkyl ester of at least one ethylenically unsaturated carboxylic acid, (a3) from 0 to 10% by weight of at least one further ethylenically unsaturated compound, data in % by weight being based on the total amount of comonomers of the relevant stage, and the (co)polymer thus obtained is reacted in a subsequent stage (B) with a further comonomer or a further mixture of comonomers comprising (b1) from 0 to 30% by weight of at least one ethylenically unsaturated carboxylic acid, (b2) from 70 to 100% by weight of at least one C 1 -C 22 -alkyl ester of at least one ethylenically unsaturated carboxylic acid, (b3) from 0 to 10% by weight of at least one further ethylenically unsaturated compound, data in % by weight being based on the total amount of comonomers of the relevant further stage.

Abstract: The invention relates to a method for producing a solution of tanning agents containing sulphone. In said method, a) a component A is produced as follows: a1) phenol is reacted with concentrated sulphuric acid or with oleum with an SO3 content of between 20 and 65 wt. %, or with a mixture of sulphuric acid and oleum with an SO3 content of between 20 and 65 wt. %, whereby the molar ratio of total sulphuric acid, calculated in the form of SO3 to phenol is between 0.7: 1 and 1.5: 1, at a temperature of between 100 and 180 DEG C to obtain a mixture containing phenolsulphonic acid, dihydroxydiphenyl sulphone and sulphuric acid, or the individual components are blended to produce a corresponding mixture; a2) said mixture is subsequently condensed at between 40 and 90 DEG C per mol of phenol units present with between 0.25 and 4 mol of urea and between 0.5 and 4 mol of an aliphatic aldehyde comprising between 1 and 6 C atoms, a3) optionally a pH value of between 4 and 5 is set by adding a base; b) a component B is produced as follows: b1) dihydroxydiphenyl sulphone is reacted with between 0.5 and 5 mol of an aliphatic aldehyde comprising between 1 and 6 C atoms and between 0.4 and 2 mol of sodium sulphite per mol of dihydroxydiphenyl sulphone, at a temperature of between 90 and 180 DEG C; b2) optionally a pH value of between 3.5 and 5.5 is set by adding an acid. c) Between 10 and 90 wt. % of component A is mixed with between 90 and 10 wt. % of component B, (the sum of A and B amounting to 100 wt. %) and if not already accomplished in steps a3) and b2), the pH value of the mixture is set at between 3.5 and 5.5.
