摘要

Copoly(diethyl vinylbenzylphosphonate/ hydroxyethyl methacrylate) [copoly(VBP-HEMA)] and copoly(diethyl vinylbenzylphosphonate/vinylbenzyI chloride) [copoly(VBP-VBC)] were prepared and their membranes crosslinked by a reaction of ethylene glycol diglycidyl ether and ethylene diamine with, respectively, hydroxyl and methylene chloride groups in their side chains. Pervaporation. (PV) and sorption of benzene-n-hexane (Bz-Hx), benzene-cyclohexane (Bz-Cx), and toluene-n-octane (Tol-n-Ot) mixtures were investigated. The membranes were in a rubbery state and preferentially permeable to aromatics. They had higher specific permeation flux and a lower PV separation factor compared with the crosslinked membranes of methacrylate copolymers with analogous pendant groups. They displayed better PV performance for Tol-n-Ot. Sorption isotherms of Bz-Hx mixtures were represented by the Flory-Rehner model. (C) 2003 Wiley Periodicals, Inc. [References: 27]
