Abstract
Polythiocarbonates were synthesized from several diphenols and thiophosgene under phase transfer catalysis conditions, using quaternary ammonium and phosphonium salts and a crown ether as catalysts, and dichloromethane as solvent. Polymers were characterized by IR and 1H NMR, and the molecular weights were estimated from inherent viscosity measurements. The influence of the catalysts and the structure of the diphenols were studied, it was found that both exert an important effect on the molecular weights. The yields were acceptable and higher than 75% in most cases.
