Abstract:
1. A fluorocopolymer which comprises: repeating units (a) based on tetrafluoroethylene and/or chlorotrifluoroethylene; repeating units (b) based on a cyclic hydrocarbon monomer, having a dicarboxylic anhydride group and an endocyclic polymerizable unsaturated group, selected from the group consisting of the following formulae (1) to (8): wherein in the formulae (2) and (5) to (8), R is a C repeating units (c) based on other monomer (excluding tetrafluoroethylene, chlorotrifluoroethylene and the cyclic hydrocarbon monomer); wherein the repeating units (a) are from 50 to 99.89 mol %, the repeating units (b) are from 0.01 to 5 mol %, and the repeating units (c) are from 0.1 to 49.99 mol %, based on the total molar amount of the repeating units (a), (b) and (c); and which has a volume flow rate of from 0.1 to 1,000 mm
