Title:
FLUOROCOPOLYMER AND PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/1991/006584
Kind Code:
A1
Abstract:
A fluorocopolymer composed of 40 to 60 mole % of fluorolefin units, 25 to 55 mole % of vinyl ester or ether units and 5 to 25 mole % of hydroxylated vinyl ether units, wherein the intrinsic viscosity as measured in an uncured state in tetrahydrofuran is 0.01 to 0.05 dl/g and the ratio of the weight-average molecular weight to the number-average molecular weight as measured with a gel permeation chromatograph is 2.0 or less. This copolymer is excellent in weathering resistance and provides a high-solid coating material which has a good applicability and gives a coating film excellent in definition.
