摘要：
A fluorocopolymer which comprises (a) polymerized units based on tetrafluoroethylene and/or chlorotrifluoroethylene, (b) polymerized units based on a fluorinated monomer (excluding tetrafluoroethylene and chlorotrifluoroethylene) and (c) polymerized units based on at least one member selected from the group consisting of itaconic acid, itaconic anhydride, citraconic acid and citraconic anhydride, wherein (a) is from 50 to 99.8 mol %, (b) is from 0.1 to 49.99 mol %, and (c) is from 0.01 to 5 mol %, based on ((a)+(b)+(c)), and which has a volume flow rate of from 0.1 to 1000 mm3/sec.
