摘要：
A new copolymer composition comprising the soft segment of an aliphatic polyester and the hard segment of a highly halogenated polyurethane containing from 3 to 36 halogen atoms is disclosed. The new halogenated polyurethane copolymer membrane has high thermal stability, and good selectivity and permeability for separation of an aromatic/saturate mixture.
