SYNTHESIS OF ALIPHATIC AND AROMATIC POLY(S-DITHIOCARBONATES) USING A PHASE-TRANSFER CATALYST

A series of aliphatic and aromatic polydithiocarbonates was prepared u sing a novel low temperature ''one-pot'' synthetic procedure employing a phase-transfer catalyst. The starting reagents were a dihalide, a d iol, and an excess of carbon disulfide. The effects of the phase-trans fer catalyst and reaction conditions on yield are reported. The struct ure and composition of the polymers were determined from infrared and ultraviolet spectroscopy and elemental analyses. The polymers were fur ther characterized by viscosity measurement and thermogravimetric anal ysis.
