Title:
PRODUCTION OF CARBOXYLATED FLUOROCOPOLYMER
Document Type and Number:
Japanese Patent JPH09255731
Kind Code:
A
Abstract:

To obtain a carboxylated fluorocopolymer which provides a water-base coating material which forms a coating film improved in appearance and physi cal properties such as weathering resistance by copolymerizing a fluoroolefin, an unsatd. carboxylic acid, and other monomers in the presence of a borate.

This copolymer is obtd. by copolymerizing a fluoroolefin, an unsatd. carboxylic acid, and other monomers in the presence of a borate, pref. an alkali or alkaline earth metal borate. The proportion of the fluoroolefin to the sum of all the monomers is pref. 20-70mol%; that of the carboxylic acid, pref. 1-30mol%; and that of the other monomers, pref. 1-50mol%. The amt. of the borate present is pref. 0.1-10 pts.wt. based on 100 pts.wt. sum of all the monomers.
