ONE-STEP POLYMERIZATION OF POLYTRITHIOCARBONATE USING PHASE-TRANSFER CATALYST

A series of aliphatic and aromatic polytrithiocarbonates was prepared using a novel ''one-pot'' synthesis procedure employing a phase-transf er catalyst. The starting reagents were either an aliphatic or an arom atic dihalide and an excessive amount of carbon disulfide. The effects of the phase-transfer catalyst and reaction conditions on yield were studied. The structure and composition of the polymers and reaction si de-products were determined from infrared, ultraviolet, H-1-NMR spectr a, and elemental analyses. The polymers were further characterized by viscosity measurement and thermal analysis.
