摘要：
The invention concerns homopolymers and copolymers of 1-vinylimidazole and a method of producing low-molecular-weight homopolymers of 1-vinylimidazole and copolymers of 1-vinylimidazole and 1-vinylpyrrolidone by the radical-mechanism polymerization of 1-vinylimidazole or mixtures of 1-vinylimidazole and 1-vinylpyrrolidone in C1 to C4 alcohol, water or a mixture of water and at least one C1 to C4 alcohol in the presence of polymerization regulators containing bound sulphur. Obtained are solutions of low-molecular-weight polymers which are low in residual monomers. The invention also concerns the use of these polymers as dye-transfer inhibiters in washing products.
