Abstract
A process for preparing a fluoropolymer by polymerizing one or more radically polymerizable monomers comprising at least one fluoroolefin monomer in the presence of a radical polymerization initiator and as case demands, an inactive fluorocarbon and chain transfer agent in a reaction field where at least one of components forming the reaction field is in a supercritical state. According to the preparation process, generation of unstable end groups of the polymer, a decrease in a purity and complicated post-treatment can be eliminated.
