The mixed matrix membranes may be cast or formed by ISAM processes, and may be present on a variety of supports including hollow fibers.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/40/091/071/0.pdf10410599502/4502/64502/77B01J31/1616B01D53/228B01D67/0079B01D69/147B01D69/148B01D71/64B01J31/1608B01J31/1633B01J31/1805B01J35/065B01J37/0219B01J37/0244B01J37/0246B01D2323/217109140
