Title:
PRODUCTION OF FLUORINE-CONTAINING POLYMER
Document Type and Number:
Japanese Patent JPH07113002
Kind Code:
A
Abstract:

PURPOSE: To provide a fluorine-containing polymer used for fluororesin coatings having good staining resistance capable of holding the characteristics weathering resistance of fluororesins and simultaneously holding an excellent appearance even when used outdoors for a long period.

CONSTITUTION: A method for producing a hydroxyl group and fluorine- containing graft polymer containing 50-95wt.% of an unsaturated group and fluorine-containing polymer comprises the first step for reacting a fluorine- containing polymer comprising a fluorinated olefin, a fatty acid vinyl ester or fatty acid isopropenyl ester, and a hydroxyl group-containing allyl ether as essential components and having a number-average mol.wt. of 1,000-20,000 (converted into polystyrene) with an unsaturated isocyanate to produce an unsaturated group and fluorine-containing polymer, and the second step for polymerizing monomers in the presence of the obtained solution to produce a graft polymer.
