    Abstract: Preparation of water soluble or water dispersible copolymer comprises either polymerizing at least a polymer (P1) having at least an anhydride reactive group, and at least a compound containing alpha , beta -ethylenically unsaturated amide group, or reacting at least a hydrolysis product of P1 with a polyolefin (P2) containing at least a anhydride group, where the reaction step takes place using a shear force. Preparation of water soluble or water dispersible copolymer comprises either polymerizing at least a polymer (P1) having at least an anhydride reactive group, and at least a compound (M1) containing alpha , beta -ethylenically unsaturated amide group of formula (R1>-C(=O)-NR2>R3>), or reacting at least a hydrolysis product of P1 with a polyolefin (P2) containing at least a anhydride group, where the reaction step takes place using a shear force. R2>CH2=CR4>; R4>H or 1-4C-alkyl; and either R1>, R3>H, (cyclo)alkyl, heterocycloalkyl or (hetero)aryl; or R1>R3>NH2lactam with 5 to 8 ring atoms. Independent claims are included for: (1) the copolymer obtained by the above process; (2) an active or effective composition comprising the copolymer and at least an active or effective material with an solubility of 10 g/l in water at 25[deg]C and 1013 mbar; (3) a method for the preparation of the aqueous active or effective composition comprising either preparing homogeneous, non-aqueous mixture containing the copolymer and the active or effective material and dispersing the obtained mixture in water, or preparing a solution of the active or effective material and the copolymer in an organic solvent having boiling point less than water, mixing the obtained mixture and removing the organic agent, or preparing the active or effective material in an aqueous solution copolymer at a temperature above the melt temperature of the active agent; and (4) a cosmetic, pharmaceutical or plant protective agent comprising the copolymer, at least the cosmetic active or effective material and optionally at least an auxiliary material.

    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.
