| titleOfInvention | Gas separating permselective membrane and preparation thereof |
| abstract | PURPOSE: To obtain a novel gas separating permselective membrane comprising a polymer based on polyurea containing silicon in the main chain thereof and to provide a process for preparing the same. n CONSTITUTION: A polymer comprising polyurea, which is obtained by reacting diamine represented by formula, for example, 2W12C, pref, 6W13C alicyclic diamine or polysiloxane-containing diamine and a compound having at least two dissocyanate groups, for example, 4W15C, pref., 6W13C dissocyanate, is formed on a microporous support to form a membrane comprising polyurea. The total thickness of the membrane and the support is at least 100Å, usually, 300W 4,000Å and selectivity of oxygen to nitrogen (oxygen permeation amount/nitrogen permeation amount) is, for example, 4.0W7.1. n COPYRIGHT: (C)1984,JPO&Japio |
