Abstract: A brief review is given of the history and technology of chlorinated rubber. The empirical formula is approximately (C10H11Cl7)n, corresponding to 65.4% Cl. The structure is complex, and includes partially chlorinated cyclohexane rings. All the Cl is released as HCl on pyrolysis. The enthalpy of formation was estimated from the reported heat of combustion as −395 kJ mol−1. For comparison, the enthalpy of formation of solid polyvinyl chloride (C2H3Cl)n was reported to be −94.6 kJ mol−1 and that of solid polyvinylidene chloride (C2H2Cl2)n was reported to be −100.4 kJ mol−1.
Keywords: chlorinated rubber, Parlon, enthalpy of formation, chlorine donors, PVC, polyvinyl chloride, polyvinylidene chloride.
