説明
<jats:title>Abstract</jats:title><jats:p>Copoly(diethyl vinylbenzylphosphonate/hydroxyethyl methacrylate) [copoly(VBP–HEMA)] and copoly(diethyl vinylbenzylphosphonate/vinylbenzyl 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–<jats:italic>n</jats:italic>‐hexane (Bz–Hx), benzene–cyclohexane (Bz–Cx), and toluene–<jats:italic>n</jats:italic>‐octane (Tol–<jats:italic>n</jats:italic>‐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–<jats:italic>n</jats:italic>‐Ot. Sorption isotherms of Bz–Hx mixtures were represented by the Flory–Rehner model. © 2003 Wiley Periodicals, Inc.
