Abstract

PURPOSE: A polypeptide having a molecular weight of 500 - 15,000 prepared by the hydrolysis of collagen is made to react with a glycidyl trialkylammonium salt I (R is methyl, ethyl; X is halogen) in an aqueous medium, in the presence of an alkali catalyst, at 150-80°C for 1 - 5 hours, and the reaction mixture is neutralized by adding an acid and made to react at 20 - 50°C for 0.5 - 2 hours. The active hydrogen in the polypeptide is substituted by the quaternary nitrogen-containing group II.
