Title: Polymers and membranes for separation of polar organic compounds from aqueous mixtures and methods of using

Abstract

A polymer having a contact angle with water that is greater than or equal to 90°. and a contact angle with 1,3-propane diol that is less than 90°. A pervaporation membrane comprising the polymer and a process for purifying a fermentation broth using a pervaporation membrane comprising the polymer is also described.
