Reaction Conditions

Reaction Steps

A 64.2% aqueous solution of N-ethylallylamine hydrochloride (hereinafter, abbreviated as EAA.HCl) was propared by adding 52.1 g of 35% hydrochloric acid to 42.58 g (0.5 mole) of N-ethylallylamine while cooling the reaction mixture. On the other hand, 28.54 g (0.5 mole) of allylamine was neutralized with 52.1 g of 35% hydrochloric acid while cooling the reaction mixture, and then the mixture was concentrated by means of rotary evaporator to obtain a 69.8% aqueous solution of allylamine hydrochloride (hereinafter, abbreviated as AA.HCl). Then, 18.94 g of the aqueous solution of EAA.HCl and 13.40 g of aqueous solution of AA.HCl, obtained above, were mixed together and heated to 60° C. Then, 0.645 g of 2,2'-azobis(2-amidinopropane) dihydrochloride was added, and a polymerization reaction was carried out at that temperature for 48 hours. After the reaction, the reaction mixture (a solution) was poured into a large amount of acetone to precipitate the reaction product. The precipitate was collect by filtration using a glass filter and dried at 50° C. under reduced pressure. Thus, a copolymer of N-ethylallylamine hydrochloride and allylamine hydrochloride was obtained.
