✦ Synopsis
Polyester having amino sulfonic acid moieties (TBES) was prepared by a liquid/solid biphase polycondensation of terephthaloyl chloride (TPC) and N,N-bis(2hydroxyethyl)-2-aminoethanesulfonic acid (BES) in trimethyl phosphate (TMP) using triethylamine (TEA) as an acid acceptor. Blends of TBES with PVA and their metal complexes with Ni 2/ and Co 2/ ions were prepared. A strong interaction was observed between TBES and PVA. An electric conductivity of 10 06 S cm 01 was attained for the blend films containing about 5 wt % water. A coordination structure with two chelate rings is proposed for the metal complex with Ni 2/ and Co 2/ ions when the molar ratio of amino sulfonic acid groups in TBES to metal ions is larger than 2. Polymer blends complexed with Ni 2/ or Co 2/ ions result in semi-interpenetrating polymer networks from chelate formation.
