PREPARATION OF MICROCAPSULATED SPHERICAL POLYMER

PROBLEM TO BE SOLVED: To obtain a microcapsulated copolymer of both a hydrophilic monomer and a hydrophobic monomer having a particle size as uniform as possible by adding the hydrophilic monomer to an aqueous phase. SOLUTION: (A) A microcapsulated hydrophobic monomer dispersed in an aqueous phase i...

Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a microcapsulated copolymer of both a hydrophilic monomer and a hydrophobic monomer having a particle size as uniform as possible by adding the hydrophilic monomer to an aqueous phase. SOLUTION: (A) A microcapsulated hydrophobic monomer dispersed in an aqueous phase is polymerized by adding (B) a hydrophilic monomer to the aqueous phase. A monoethylenically unsaturated compound having
