Specialty polymeric membranes. 1. Modified polybutadiene membranes for alcohol separation

Pervaporation of lower alcohol/water mixture (alcohol: methanol, ethanol, or 1-propanol) through uncrosslinked and crosslinked polybutadiene membranes was investigated. Crosslinked polybutadiene membranes permeated lower alcohols in preference to water indicating that polybutadiene is a candidate for permselective membranes for the separation of alcohol/water mixtures.
