摘要： Method for regenerating an auxiliary filtering agent, representing a co-extrudate of water insoluble polyvinyl pyrrolidone and thermoplastic polymers, by treatment with aqueous lye and with enzymes, wherein the auxiliary filtering agent is first subjected to a treatment with aqueous lye. A treatment with an enzyme solution follows. A further treatment with aqueous lye follows, and, if necessary, a treatment with a surfactant is carried out.

摘要： The invention relates to water-soluble or water-dispersible, film-forming graft polymers which are obtained by radical polymerization of (a) the vinyl esters of aliphatic C1-C24 carboxylic acids in the presence of (b) the polyethers having an average molecular weight (number average) of at least 300 of the general formula (I), wherein the variables independently have the following meanings: R1 represents hydroxy, amino, C¿1?-C24 alkoxy, R?9¿-COO-, R9-NH-COO-, a polyalcohol group; R2 to R7 represent -(CH¿2?)2-, -(CH2)3-, -(CH-2)4-, -CH2-CH(CH3)-, -CH2-CH(CH2-CH3)-, -CH2-CHOR?10-CH¿2-; R8 represents hydrogen, amino-C¿1?-C6 alkyl, C1-C24 alkyl, R?9-CO-, R9¿-NH-CO-; R9 represents C¿1?-C24 alkyl; R?10¿ represents hydrogen, C¿1?-C24 alkyl, R?9¿-CO-; A represents -CO-O-, -CO-B-CO-O, -CO-NH-B-NH-CO-O-; B represents -(CH¿2?)t- or optionally a substituted arylene; n is 1 or, if R?1¿ is a polyalcohol group, n is 1 to 8; s is 0 to 500; t is 1 to 12; u is 1 to 5000; v is 0 to 5000; w is 0 to 5000; x is 1 to 5000; y is 0 to 5000; and z is 0 to 5000. The inventive polymers can be used as coating agents, matrix formers and/or packaging materials for agrochemicals.
