By photochemical chlorination chlorine was substituted on the gem ‐dimethyl groups of the polyterephthalate and polycarbonate of 2,2,4,4‐tetramethyl‐1,3‐cyclobutanediol, the polyterephthalate of 2,2‐dimethyl‐1,3‐propanediol, and the polycarbonate of 4,4′‐isopropylidenediphenol (bisphenol A). The factors affecting polyester degradation, the efficiency of chlorination, and the degree of chlorination were investigated, and the effects of chlorine content on the solubility, flammability, density, hydrolytic stability, thermal stability, tensile properties, electrical properties, and heat‐distortion temperatures of cast films were determined. The chlorinated polyesters of particular interest, because of their properties, are the polycarbonates of 2,2,4,4‐tetramethyl‐1,3‐cyclobutanediol and bisphenol A.
