Polytrialkylgermylpropyne polymers and membranes |
摘要 |
The present invention is a group of new polymers and treated, semi-permeable, polymeric membranes made from the new polymers, having improved selectivity for separating components of a gas mixture. The membrane is provided by fluorinating a polymer cast into membrane form, having the general structural formula: <IMAGE> wherein R1 is H or a C1-C2 alkyl group; R2 and R3 are independently linear or branched C1-C6 alkyl groups; R4 is a linear or branched C1-C12 alkyl or aryl group; X is a C1-C3 alkyl group or phenyl; m is at least 100; and n is 0 or 1.
