ABSTRACT:
A fluorocopolymer which comprises (A) polymerized units based on tetrafluoroethylene, (B) polymerized units based on ethylene and (C) polymerized units based on itaconic anhydride or citraconic anhydride, wherein the molar ratio of (A)/(B) is from 20/80 to 80/20, and the molar ratio of (C)/((A)+(B)) is from 1/10000 to 5/100, and which has a volume flow rate of from 1 to 1000 mm3/sec. The fluorocopolymer is excellent in the fuel barrier properties and in the adhesive properties to a non-fluorinated polymer.
