Polyimide blends for gas separation membranes
Abstract
The present invention offers the selectivity gas penetration film which has the combination which was excellent in permeability and selectivity. These polymer is defined more as details by chemical structure in this indication including the コポリ imide of Type 1 by which the membranous composite was uniformly mixed with the コポリ imide of Type 2. The present invention also offers the method of separating the ingredient of a gas mixing thing using the film of the above-mentioned コポリ imide blend.
