SYNTHESIS, CHARACTERIZATION, AND GAS TRANSPORT PROPERTIES OF NEW COPOLY(ETHER-AMIDE)S CONTAINING BENZOPHENONE AROMATIC ISOPHTHALIC SEGMENT

Three new copoly(ether-amide)s based on polyether segments of different molecular weight (average molecular weight 400, 900 and 2000 g/mol) and polyamide segments obtained from 4,4’-diamine benzophenone (DBF) and isophthalic acid (ISO) are reported. The resulting new copoly(ether-amide)s h...
