抄録

Polythioesters have recently been attracted attention due to their interesting characteristics, such as poor solubility against organic solvents and higher heat stability compared to polyoxyesters. Polythioesters were synthesized by the direct polycondensation of 1,6-hexanedithiol and diacid diesters having a variety of methylene lengths using lipase CAas a catalyst. The obtained polythioesters showed a higher melting temperature compared to those of the corresponding polyoxyesters. The 1,6-hexanedithiol and diacid diesters were reacted in n-nonane using lipase CA to produce cyclic oligomers with an Mw of a few hundreds. Synthesis of polythioester was studied using these cyclic oligomers. A high-molecular weight polythioester having an M w of about 120,000 was produced through the ring-opening polymerization using lipase CA.
