Agent for improving surface quality of paper |
摘要 |
An agent for improving surface quality of paper comrising an acrylamide resin composition obtained by hydrolyzing an acrylamide resin which is obtained by polymerizing an acrylamide monomer in the presence of a urea compound, or copolymerizing an acrylamide monomer and an acrylonitrile monomer; an acrylamide monomer and a cross-linking agent; or an acrylamide monomer, an acrylnitrile monomer and a cross-linking agent in the presence of a urea compound. This agent provides paper with excellent surface strength, tensile strength and internal strength far better than conventional paper quality improving agents./!
