Title:
MUCILAGINOUS AGENT FOR MAKING PAPER, METHOD FOR MAKING PAPER AND PAPER
Document Type and Number:
Japanese Patent JP3452505
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain mucilaginous agent which is used for making paper, can impart dispersibility to paper fibers without coagulating the paper fibers, even when used together with a cationic agent on the making of the paper, and can efficiently and stably make paper having good texture and excellent touch, to provide a method for making paper which uses the mucilaginous agent for making the paper, and to provide the paper made by the method for making the paper.
SOLUTION: This mucilaginous agent for making paper comprises (meth) acrylamide monomer units and N-vinylcarboxylic acid amide monomer units. Nonionic monomer units may further be introduced to the copolymer. The copolymer preferably comprises 30 to 98 wt.% of (meth)acrylamide monomer units, 2 to 70 wt.% of N-vinylcarboxylic acid amide monomer units and 0 to 40 wt.% of nonionic monomer units. The N-vinylcarboxylic acid amide is preferably N-vinylacetamide. A solution containing the mucilaginous agent in an amount of ≥15 wt.% may be used.
