PAPER MADE BY USE OF CATIONIC ACRYLAMIDE POLYMER

摘要

PROBLEM TO BE SOLVED: To obtain paper made by the use of a cationic acrylamide polymer obtained by the Hofmann degradation reaction of an acrylamide polymer at a high temperature in a short time. SOLUTION: This paper is made by the use of a cationic acrylamide polymer obtained by reacting an acrylamide polymer with a hypohalite salt in an alkaline region above a pH of at least 11 at a temperature (T) of 50-110 deg.C for a short time (t) below defined. e<15> ,<150/(273+> T<)>×2.5×10<-20> <=(sec)<=e<15> ,<150/(273+> T<)>×10<-18> +30. 30. The paper itself excellent in paper strength can be produced.
