TETRAFLUOROETHYLENE COPOLYMER

摘要

Provided is a tetrafluoroethylene copolymer consisting of a unit based on tetrafluoroethylene and a unit based on a monomer represented by CF2=CFOR<f1>R<f2> (where R<f1> is a polyfluoroalkylene group which may contain an etheric oxygen atom and R<f2> is a polyfluorocycloalkyl group which may contain an etheric oxygen atom), wherein a content of the latter is from 0.005 to 0.5% by mass. The tetrafluoroethylene copolymer is excellent both in paste extrudability and in heat resistance, has characteristics such as excellent transparency of a molded product, and is suitably applicable to paste extrusion and compression molding.
