Abstract

Following our earlier work on PP/PS immiscible blends, the morphologies of blends and microporous membranes of hydrophobic poly(4-methyl-1-pentene)(TPX)/ hydrophilic polyethylene vinyl alcohol copolymer(EVOH) immiscible blend systems prepared in continuous extruders are investigated. The EVOH can form a well-distributed minor phase with domains having dimensions around 1∼5jun by adding compatibilizing copolymer Lotarder®AX8950. The immiscible blend systems are extruded through a sheet die and then stretched to make flat, solvent-resistant microporous membranes suitable for ultrafiltration applications.
