Title:
PREPARATION OF AQUEOUS EMULSION OF SELF-DISPERSING FLUORINATED RESIN
Document Type and Number:
Japanese Patent JPH02147601
Kind Code:
A
Abstract:
PURPOSE:To obtain an aq. emulsion of a resin with no foambility, high surface tension and excellent water resistance by adding water to a reaction product obtd. by soln.-polymerizing a monomer mixture contg. a specified monomer and a fluorinated monomer and distilling a solvent out. CONSTITUTION:A monomer mixture consisting of 0.5-60wt.% monomer (A) having a salt-forming group or a polyalkylene oxide group and a radical- polymerizable double bond, 5-99.5wt.% fluorinated monomer (B) having a radical- polymerizable double bond and 0-94.5wt.% monomer (C) which is different from monomers (A) and (B) and has a radical-polymerizable double bond is soln.- polymerized in an alcohol or ketone solvent. After, if necessary, a neutralizing agent is added to the obtd. reaction product, water is added thereto and the alcohol or ketone solvent is distilled out therefrom to obtain an aimed aq. emulsion.
