Title:
EMULSIFYING DISPERSANT FOR ROSIN MATERIAL AND ROSIN EMULSION SIZING AGENT FOR PAPER MAKING CONTAINING THAT DISPERSANT
Document Type and Number:
Japanese Patent JP3281027
Kind Code:
B2
Abstract:
PURPOSE: To obtain a dispersant suitable for preparation of a rosin emulsion sizing agent by using an emulsifying dispersant consisting of a saponified compound material obtd. by the reaction of an anionic copolymer of styrene, a (meth)acrlkate, acrylic acid and methacrylic acid and a cationic monomer of a specified structure.
CONSTITUTION: This dispersant consists of a compound material obtd. by the reaction of 100 pts.wt. of an anionic copolymer and 0.5-10 pts.wt. of a cationic monomer expressed by formula I or II. The anionic copolymer consist of, by monomer weight, 50-70% styrene, 10-30% (meth)acrylate, 10-15% acrylic acid, and 10-15% methacrylic acid. In formula I, R1 is H or CH3, R2 and R3 are H, CH3 or C2H5, X is O or NH, and Y is C2H4 or C3H6. In formula II, R1 is H or CH3, R2 and R3 are H, CH3 or C2H5, R4 is CH3, C2H5, C6H5CH2, etc., Z is an inorg. acid or org. acid residue such as C1 and CH3-COO.
