| titleOfInvention | Production of selectively permeable composite membrane for separation of gas |
| abstract | PURPOSE: To obtain a composite membrane having good gas permeability by polymerizing a diisocyanate component contg. a prescribed amt. of a specific component and a compd. having two amino groups on a microporous backing membrane thereby forming polyurea film. n CONSTITUTION: A diisocyanate component and a compd. having two amino groups selected from primary and secondary amino groups are polymerized on a microporous backing membrane. Said component contains ≥50mol% component expressed by the equation I [(l) and (m) are the same or different 2W10 integers, (n) is 0 or 1W200 inteters, R 1 WR 6 are the same or different 1W10C hydrocarbon groups, Y 1 and Y 2 are the same or different groups expressed by the equation II(R 7 is H or 1W6C hydrocarbon groups), -0- or -S-, X 1 and X 2 are the same or different 2W20C org. groups]. The composite membrane with the polyurea film obtd. by the above-mentioned method has excellent gas permeability. n COPYRIGHT: (C)1984,JPO&Japio |
