Copolymerization results of ethylene with M1–M3 using C4/MAO indicate that M1–M3 are well tolerated by both the cationic active species of C4 and MAO cocatalyst, giving rise to the copolymers with high levels of activity and molecular weight. Inspection of the aliphatic region of the 13C NMR spectra of the copolymers (P1–P3) having ca. 11 mol% of M1–M3, respectively, reveals the presence of isolated comonomer units
