Crosslinked-type copolymer polymer membrane comprising the same gas separation membrane comprising the polymer membrane and manufacturing method of the crosslinked-type copolymer

摘要

The present invention relates to a cross-linked copolymer, a polymer membrane comprising the same, a gas separation membrane comprising the polymer membrane, and a method for producing the cross-linked copolymer, and more particularly, polydimethylsiloxane in a main chain including a skeleton of a glycol-based compound. By synthesizing a crosslinked copolymer by ring-opening metathesis polymerization of the first side chain containing Selectivity can be improved at the same time. In addition, the cross-linked copolymer of the present invention has a low crystallinity and has excellent mechanical properties such as film formability and flexibility, so that it can be applied to various fields using the same.
