View page
US Patent:
49684701, Nov 6, 1990
Filed:
Nov 15, 1989
Appl. No.:
7/436586
Inventors:
Stephen C. Lynch - Center Valley PA
James K. Smith - Baton Rouge LA
John W. McTopy - LaPlace LA
Pushpinder S. Puri - Macungie PA
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
B01D 7126
B29C 4700
US Classification:
26417714
Abstract:
Asymmetric polyacetylene polymer membranes having both improved selectivity and improved flux are provided by a process which comprises forming a solution containing from about 1 to about 5% by weight of a polyacetylene polymer in any suitable solvent therefor, forming the solution into a thin film and quenching the film in an aqueous bath in the presence of from about 0. 002 to about 0. 4% by weight of the quench bath of surfactant with an HLB value of 11 to 15. Additionally, the polyacetylene polymer solution contains a swelling agent at about 1% to about 10% by weight of polyacetylene polymer solution.
