  The present invention discloses a new type of polyimide membrane with high permeances and high selectivities for gas separations and particularly for CO 2 /CH 4 and H 2 /CH 4 separations. The polyimide membranes have CO 2 permeability of 50 Barrers or higher and single-gas selectivity for CO 2 /CH 4 of 15 or higher at 50° C. under 791 kPa for CO 2 /CH 4 separation. The polyimide membranes have UV cross-linkable functional groups and can be used for the preparation of UV cross-linked polyimide membranes having CO 2 permeability of 20 Barrers or higher and single-gas selectivity for CO 2 /CH 4 of 35 or higher at 50° C. under 791 kPa for CO 2 /CH 4 separation.
