Acylated polyallylamine and process for producing the same

摘要

Acylated polyallylamine, whose cation density is controlled as desired, is easily produced by treating a solution of polyallylamine having a polymerization degree of at least 10 with a carboxylic acid anhydride such as acetic anhydride. Also, it is suggested that the present acetylated polyallylamine is used as a reactive dye-fixing agent, a direct dye-fixing agent, etc.
