Fluorine-containing resin molded article and method for producing a fluorine-containing copolymer composition

摘要

Fluorine-containing copolymer of high molecular weight having a melt viscosity of the melting point + 15 ℃ is 1500~35000Pa · s, and repeating units based on ethylene and repeating units based on tetrafluoroethylene (A), a of the melting point + 15 ℃ melt viscosity of 50~3000Pa · s, melt viscosity at the melting point + 15 ℃ fluorinated copolymer (A) is one-fifth of the melt viscosity at the same temperature fluorine-containing copolymer (A) The less, the fluorine-containing copolymer of low molecular weight having repeating units based on ethylene and repeating units based on tetrafluoroethylene fluorinated copolymers from (A) (B), and fluorine-containing copolymer (A) and a solvent capable of dissolving the fluorine-containing copolymer (A) and (B) at a temperature below the melting point of (B) fluorine-containing copolymer and (A) (B) a mixture comprising a (C) and (D) There is heated to a temperature above dissolving solvent (C), and a solution state, then the process for producing a fluorine-containing copolymer composition to remove the solvent (C).
