    • The invention concerns powdery porous polymers which contain N-vinylimidazol units and are obtained by the radically initiated polymerization in the manner of precipitation polymerization of: a) between 5 and 100 wt.% of at least one N-vinylimidazol of formula (I) in which R , R and R are identical or different and stand for H, C1 - C4 alkyl, monomers of formula (II), in which R and R are identical or different and stand for H, C1 - C4 alkyl or form with one another a ring comprising between 3 and 5 methylene groups, N-vinyloxazolidone, N-vinyltriazol, 4-vinylpyridine-N-oxide or a mixture of said monomers; b) between 0 and 95 wt.% of other copolymerizable monoethylenically unsaturated monomers; and c) between 0 and 50 wt.% of at least one monomer with at least two ethylenically unsaturated non-conjugated double bonds; in an aqueous solution which contains between 0.5 and 30 wt.% of at least one electrolyte and, relative to the monomers used, between 0.5 and 80 wt.% of at least one surfactant. The invention further concerns processes for their preparation and the use of the resultant powdery porous polymers containing N-vinylimidazol units as washing agent additives in order to inhibit dye-transfer during the washing process.

    • The invention concerns water-soluble copolymers obtained by the radically initiated solution polymerization of: a) between 10 and 99.5 wt % of at least one vinylimidazole of formula (I), in which R , R and R are identical or different and stand for H, C1 to C4 alkyl, monomers of formula (II), in which R and R are identical or different and stand for H, C1 to C4 alkyl or form with one another a ring of between 3 and 5 methylene groups, N-vinyloxazolidone, N-vinyltriazole, 4-vinylpyridine-N-oxide or mixtures of said monomers; b) between 0 and 89.5 wt% of other copolymerizable monoethylenically unsaturated monomers; and c) between 0.5 and 30 wt% of at least one monomer acting as cross-linking agent with at least two ethylenically unsaturated non-conjugated double bonds. The polymerization is carried out in water and/or polar organic solvents in the presence of polymerization control agents, between 0.1 and 5 parts by weight of polymerization control agents being used per 1 part by weight of cross-linking agent. The invention also concerns a process for preparing said copolymers by radically initiated solution polymerization of the monomers in the presence of polymerization control agents, and the use of the copolymers as additives for washing products.
