PURPOSE: To prepare film for separation of fluid having thin film-forming property and mechanical strength by crosslinking a copolymer of a specified vinyl compd. with another vinyl compd. contg. groups capable of reacting with a compd. having active hydrogen, or with a vinyl compd. having active hydrogen. n CONSTITUTION: A copolymer of a vinyl compd. I expressed by the formula 1 such as tris(trimethylsiloxy) silylpropyl methacrylate with a vinyl compd. II such as glycidyl methacrylate, etc., is crosslinked with a compd. having ≥2 active hydrogen atoms such as 1,10-decamethylenediamine, etc.; or a copolymer of the vinyl compd. I with a vinyl compd. III such as acrylamide, etc., is crosslinked with a compd. having ≥2 groups capable of reacting with a compd. having active hydrogen atoms such as hexamethylene diisocyanate, etc. The obtd. crosslinked film exhibits high selectivity for liquid compds. from gaseous compds. n COPYRIGHT: (C)1986,JPO&Japio |
