The preparation of poly(1,2‐dichloroethylene), an unknown material that has been expected to be a superb engineering thermoplastic, was explored. The ring‐opening metathesis polymerization of cis ‐3,4‐dichlorocyclobutene quantitatively yielded a white linear polymer with CHClCHClCHCH repeating units. However, its subsequent addition chlorination could not be made to occur to a detectable level. Steric hindrance and/or electronic deactivation due to the inductive effect of Cl apparently made the chlorination impossible. Furthermore, thermal degradation studies of a series of model compounds indicated that polymers containing (CHCl) n ( n ≥ 3) structures would have low thermal stabilities. J. VINYL ADDIT.
