| titleOfInvention | Paper strength agent |
| abstract | PROBLEM TO BE SOLVED: To provide a paper strength enhancer capable of obtaining a good effect in a wide pH range from acidic papermaking to neutral papermaking, and to achieve a desired degree of crosslinking even when a large amount of a crosslinking agent is added during production. The present invention provides a paper strength agent comprising a polyacrylamide-based polymer which can be easily adjusted. SOLUTION: A polycationic crosslinking agent produced by reacting epihalohydrin with one or more amines from ammonia, a primary amine or a secondary amine and a tertiary amino group-containing vinyl monomer, (meth) This can be achieved by a paper strength agent comprising an amphoteric copolymer containing acrylamide and an α, β-unsaturated carboxylic acid or a salt thereof as a constituent monomer component. |
