Cross-linked hydroxy terminated polybutadiene (HTPB)-based polyurethaneurea (PU), HTPB-DVB-PU, was synthesized by a three-step polymerization process. It was firstly used as membrane material to recover aroma, ethyl acetate (EA), from aqueous solution by pervaporation (PV). The effects of the conten
## Abstract **BACKGROUND:** To use butanol as a liquid fuel and feedstock, it is necessary to establish processes for refining lowβconcentration butanol solutions. Pervaporation (PV) employing hydrophobic silicalite membranes for selective recovery of butanol is a promising approach. In this study,
