Monomer reactivity ratios determined for the copolymerization of tert-butyl N-vinylcarbamate (rA = 0.55 ± 0.05) with phenyl N-vinylcarbamate (rB = 2.08 ± 0.15) indicate that the monomer units are distributed randomly along the polymer chains. The following sequence of reactions was used to cause intersequence cyclization between tert-butyl N-vinylcarbamate and phenyl N-vinylcarbamate units in the copolymers. The extent of cyclization obtained was in accord with that expected for random copolymers.
