Title:

PRODUCTION METHOD FOR FLUORINE-CONTAINING COPOLYMER COMPOSITION, COATING COMPOSITION, MOLDED ARTICLE AND ARTICLE HAVING COATING FILM

Document Type and Number:

WIPO Patent Application WO/2011/129407

Kind Code:

A1

Abstract:

Disclosed is a method for a fluorine-containing copolymer composition wherein a fluorine-containing copolymer (A) which has repeating units derived from ethylene and repeating units derived from tetrafluoroethylene, and a thermoplastic resin (B) can be uniformly mixed at a relatively low temperature. Further disclosed are a coating composition which can form a coating film having the properties of the fluorine-containing copolymer (A) and the thermoplastic resin (B), a molded article and an article having the coating film. The disclosed method is for a fluorine-containing copolymer composition which contains a fluorine-containing copolymer (A), a thermoplastic resin (B) (with the exception of the fluorine-containing copolymer (A)), and a medium (C) which can at least dissolve the fluorine-containing copolymer (A). The fluorine-containing copolymer (A) and the thermoplastic resin (B) are mixed in the medium (C) at a temperature that is at least the dissolution temperature at which the fluorine-containing copolymer (A) dissolves in the medium (C) but that does not exceed the melting point of the fluorine-containing copolymer (A).
