ROMPs of strained monomers. After quenching with ethyl vinyl ether, the polymer was isolated by precipitation in methanol. aDetermined by GPC in tetrahydrofuran (THF) relative to a polystyrene standard. bDetermined by GPC in N,N-dimethylformamide (DMF) relative to a polystyrene standard. cTheoretical Mn was calculated by assuming quantitative conversion. dBn = Benzyl; TBS = tert-Butyldimethylsilyl
