All-polymeric membranes

Poly[l-(trimethylsilyl)-l-propyne] (PMSP) is a typical glassy polymer at room temperature that was first syndiesized by Masuda and Higashimura in the 1980 s (1). Recently, membranologists have studied their gas permeation properties. The PMSP membrane has the highest gas permeability of all polymeric membranes. Therefore, this polymer is expected to have potential utiliQ in industrial applications such as the separation of oxygen and nitrogen from air. [Pg.326]

All polymeric membranes and modules have admissible tan-perature of operation. For most of them, this temperature is... [Pg.669]

Noncellulosic Synthetic Membranes In the dialysis field, the term synthetic membrane is used to denote all polymeric membranes that are not cellulose based. Table 19.2 lists the various synthetic membranes that are commercially available. Polymers such as polyacrylonitrile (PAN), polymethylmethacrylate (PMMA), and ethylene vinyl alcohol (EVAL) copolymer were adapted from the textile industry, while polymers such as polysulfone, polycarbonate, and polyurethane were developed as engineering plastics. Synthetic membranes with high water permeability were developed in the 1960s... [Pg.527]
