Title:
PRODUCTION OF HYDROPHILIC FINE GRAIN
Document Type and Number:
Japanese Patent JPH04132705
Kind Code:
A
Abstract:
PURPOSE:To obtain fine grains having excellent water absorption in drying and antistatic properties after film forming by (co)polymerizing an acrylamide (derivative) with p-styrene sulfonic acid (salt), (meth)acrylic acid (salt), etc., in a water-miscible organic solvent, etc., in the presence of a soluble resin. CONSTITUTION:In a water-miscible organic solvent or a mixed solvent of water- miscible organic solvent/water, a homogeneous polymerization of a monomer soluble in the above-mentioned solvent(s) and selected from (A) an acrylic amide (derivative), (B) p-styrene sulfonic acid (salt) and (C) (meth)acrylic acid (salt) or copolymerization of (D) a vinyl compound [preferably styrene (derivative), (meth)acrylic acid ester, (meth)acrylonitrile or maleic acid (derivative)] polymerizable with the monomers of the components A to C is carried out in the presence of a resin soluble to the above-mentioned organic solvent to provide the aimed fine grains.
