Polymers of alkyl-1-vinylimidazoles

Abstract

(57) -- the polymer of summary アルキル *1* vinyl imidazole, and (a) -- at least one アルキル *1* vinyl imidazole 10*100% of the weight, and (b) 1* vinyl pyrrolidone and 1* vinyl caprolactam -- it 1-*-vinyl-doria-ゾール (ing) and, 1* vinyl imidazole, 1* vinyl オキサゾリジノン, or these mixtures 0*90 % of the weight, (c) other mono-ethylene nature unsaturated monomers 0*30 % of the weight and (d) -- monomer containing at least two mono-ethylene nature unsaturated double bonds The monomer mixture which consists of 0*10 % of the weight, How to manufacture the polymer of アルキル *1* vinyl imidazole by carrying out radical polymerization under existence of a polymerization regulator underwater and in of at least one C*C* alcohol or these mixtures, And it is used as an additive agent to the detergent for controlling the migration in a cleaning process of the polymer which carries out polymerization introduction and contains at least 10 % of the weight of アルキル *1* vinyl imidazole.
