This invention provides a cyclic ether copolymer such as a cyclic ether copolymer excellent in solubility in solvents and easy to form uniform thin films therefrom. The present invention relates to a cyclic ether copolymer obtained from a 1,3-dioxole ring structure-containing compound represented by the following general formula (I) and an ethylenically unsaturated monomer:
(wherein R
1
and R
2
are the same or different and each represents F, H, Cl or a perfluoroalkyl group containing 1 to 5 carbon atoms and X
1
and X
2
are the same or different and each represents F, H, Cl or —OR
3
, and R
3
represents a perfluoroalkyl group containing 1 to 5 carbon atoms, provided that at least one of R
1
and R
2
is F or a perfluoroalkyl group containing 1 to 5 carbon atoms), which compolymer has a glass transition point of 100 to 135° C. and an intrinsic viscosity of 0.01 to 0.4 dl/g as determined at 35° C. in perfluoro-2-butyltetrahydrofuran.
