Title:
カチオン性表面サイズ剤の製造方法および該方法により得られるサイズ剤
Document Type and Number:
Japanese Patent JP5879042
Kind Code:
B2
Abstract:
The present invention relates to a method for producing a cationic surface sizing agent, and contains a first step of obtaining a copolymer (A) by solution-polymerizing a monomer mixture containing a monomer having a tertiary amino group (a), a specific (meth)acrylic acid ester (b) and styrenes (c) in the specific proportion in the presence of a chain transfer agent; a second step of obtaining a copolymer (B) by polymerizing the copolymer (A) and a hydrophobic monomer (d), in order to have a specific proportion of the copolymer (A), in an oxidation-reduction system using a water-soluble free-radical initiator and a heavy metal salt in the absence of a surfactant; and a third step of obtaining a quaternary ammonium salt of the copolymer (B) by quaternizing a tertiary amino group present in the copolymer (B).
