Polymers of alkyl-1-vinylimidazoles and processes for the production thereof by the radical polymerisation of monomer mixtures comprising: (a) 10 to 100 wt. % at least one alkyl-1-vinylimidazole and (b) 0 to 90 wt. % 1-vinylpyrrolidone, 1-vinylcaprolactam, 1-vinyltriazole, 1-vinylimidazole, 1-vinyloxazolidinone or mixtures thereof, (c) 0 to 30 wt. % other monoethylenically unsaturated monomers and (d) 0 to 10 wt. % a monomer containing at least 2 monoethylenically unsaturated double bonds, in water, and at least one C1-C4 alcohol or mixtures thereof in the presence of polymerisation regulators. Also disclosed is the use of polymers, at least 10 wt. % of which is an alkyl-1-vinylimidazole incorporated in the polymer, as an additive to detergents to prevent colour transfer during the wash. |
