Title:
懸濁重合により製造される溶融成形可能なテトラフルオロエチレン/フッ化ビニルエーテルコポリマー
Document Type and Number:
Japanese Patent JP4685000
Kind Code:
B2
Abstract:
Melt-fabricable, tough copolymer of tetrafluoroethylene and fluorinated vinyl ether is produced in a suspension polymerization process by copolymerizing tetrafluoroethylene and fluorinated vinyl ether in a pressurized, agitated reaction vessel which contains aqueous medium, free radical initiator, and a telogen, the aqueous medium being essentially free of fluorine containing organic solvent. The contents of the reaction vessel are agitated during polymerization sufficiently to coagulate copolymer of tetrafluoroethylene and fluorinated vinyl ether. The melt-fabricable, tough copolymer having a melt viscosity of less than about 1x106 Pa.S is isolated directly from the reaction vessel.
