Abstract

We describe results relating to the effect of halide counterion in the ROMP of a permanently cationic exo‐7‐oxanorbornene derivative. Statistical copolymerizations of exo‐benzyl‐[2‐(3,5‐dioxo‐10‐oxa‐4‐aza‐tricyclo[5.2.1.0^2,6]dec‐8‐en‐4‐yl)ethyl]dimethyl ammonium bromide/chloride were conducted at different molar ratios and the polymerizations evaluated with respect to their kinetic features, as well as their molecular mass profiles, as a function of conversion, and the ability to produce materials with narrow molecular mass distributions. The polymerization characteristics are rationalized in terms of the in situ formation of the mixed Grubbs' derivative RuClBr(PCy₃)₂CHPh and/or the dibromo analog RuBr₂(PCy₃)₂CHPh.
