Fluorocopolymer composition and its production process

摘要

To provide a composition comprising a fluorocopolymer such as an ethylene/tetrafluoroethylene copolymer which can be produced at a relatively low temperature, and its production process.;A fluorocopolymer composition which comprises a fluorocopolymer such as an ethylene/tetrafluoroethylene copolymer and a fluorinated aromatic compound having a melting point of at most 230° C. and having a fluorine content in the compound of from 5 to 75 mass %, and is in a solution state at a temperature of at most the melting point of the fluorocopolymer, and a process for producing the fluorocopolymer composition, which comprises a step of dissolving the fluorocopolymer in a solvent containing the fluorinated aromatic compound at a temperature of at most the melting point of the fluorocopolymer.

1. A fluorocopolymer composition having a dissolution temperature which comprises:
0.1 to 80 mass % of a fluorocopolymer comprising 85-99.9 mol % in total of repeating units based on ethylene and repeating units based on tetrafluoroethylene relative to 100 mol % repeating units in said fluorocopolymer, and 20 to 99.9 mass % of a fluorinated aromatic compound having a melting point of at most 230° C. and having a fluorine content in the compound of from 5 to 75 mass %,wherein said composition forms a solution at said dissolution temperature and wherein said dissolution temperature is less than the melting point of the fluorocopolymer.
