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‐transfer catalyst. The starting reagents were either an aliphatic or an aromatic 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 side‐products were determined from infrared, ultraviolet, ¹H‐NMR spectra, and elemental analyses. The polymers were further characterized by viscosity measurement and thermal analysis. © 1993 John Wiley & Sons, Inc.
