Abstract
To synthesize a series of periodic copolymers containing simple α-olefins, the alternating copolymerization of propylene (P) with methyl α-chloroacrylate (MCA) was examined. An alternating P–MCA copolymer could hardly be obtained by conventional procedures where organoaluminium chlorides alone were used as complexing reagents. The addition of vanadium oxytrichloride or acetylacetonate as the second catalyst provided the well-defined alternating P–MCA copolymer. The P(P-alt-MCA) was found to have coisotacticity (σ) of 0.67 by NMR analysis and glass transition temperature (Tg) of 56°C by DSC.
