Abstract: Abstract A new monomer of the AB type, 5-carboxy-1,3-phenylene-5′-hydroxy-1′,3′-phenylene-32-crown-10 (5), was synthesized. Direct polymerizations of bis(5-hydroxy-1,3-phenylene)-32-crown-10 (13), an AA diphenolic macrocyclic monomer, with BB diacid monomer bis(5-carboxy-1,3-phenylene)-26-crown-8 (14) and its larger analog bis(5-carboxy-1,3-phenylene)-32-crown-10 (16) were… read more here.
