Abstract
Composite membranes were prepared for membrane/cold condensation process for recovery of unreacted olefin monomer from the polyolefin polymerization process by solution coating and plasma polymerization processes. Poly(dimethylsiloxane) (PDMS) solution was coated on polysulfone (PSF) support and increase of prepolymer content in solution made more dense membrane structure to result in the increase of separation factor while absolute flux decreased. Permeation of organic materials through the composite membranes follows the sorption and diffusion mechanism, which brought about the results that separation factor increased with critical temperature of the organic materials, and that flux increased with the increase of the molar volume. Crosslinking period affected the permeation characteristics. Other types of composite membranes were fabricated by plasma polymerization of siloxane materials on polypropylene (PP) and PSF supports. PP was tested as a support for composite membranes, which had not been used so far in solution coating process, and plasma polymerization made the composite membranes equivalent performances to those of membranes prepared by solution coating process.
