Title:
ポリオルガノシロキサン/有機ポリマー複合粒子の水系分散体およびその製造方法
Document Type and Number:
Japanese Patent JP4771029
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an aqueous dispersion of polyorganosiloxane/organic polymer composite particles which, when used for a coating material, is excellent in craze resistance in drying and excellent in adhesiveness and resistances to weather, water, and staining; and a production method of the same. SOLUTION: This aqueous dispersion is prepared by causing (A) 1 pt.wt. seed polymer particles having a wt. average mol.wt. of 500-30,000 to absorb (B) 1-50 pts.wt. at least one silane component selected from among organosilanes, hydrolyzates of the organosilanes, and condensates of the organosilanes and (C) 1-100 pts.wt. free-radically polymerizable monomer in an aqueous medium and subjecting the silane component (B) to hydrolysis and condensation conditions and the free-radically polymerizable monomer to free- radical polymerization conditions.
