Document Type and Number:
Japanese Patent JP5573162
Kind Code:
B2
Abstract:
To provide a process for producing a thermoplastic fluororesin having a high melt tension and being excellent in blow moldability, etc. A process for producing a thermoplastic fluororesin comprising a fluoropolymer having a branched structure, which comprises a step of polymerizing a monomer (A) having a radical generating group (x) and an addition polymerizable double bond, and a monomer (B), under polymerization conditions under which the radical generating group (x) is not decomposed, to produce a fluoropolymer (X), and a step of polymerizing a monomer (C) in the presence of the fluoropolymer (X) under polymerization conditions under which the radical generating group (x) is decomposed, to form a fluoropolymer (Y) having a branched structure (provided that each of the monomer (B) and the monomer (C) comprises one or more monomers having an addition polymerizable double bond, at least one of the monomers having an addition polymerizable double bond being a fluoromonomer, and is such a monomer that a polymer of only the monomer is a crystalline fluoropolymer; and the monomer (B) and the monomer (C) may be the same).
