METHOD FOR POLYMERIZATION OF alpha-pinene OR A MIXTURE OF alpha-pinene AND OTHER TERP MONOMERS AND CATALYST SYSTEM FOR USE IN THIS

摘要

There is provided a process for cationically polymerizing or co-polymerizing batchwise or continuously alpha -pinene by adding alpha -pinene either alone or in admixture with other terpene monomers, incrementally to a catalyst system comprising an aluminum halide and an antimony halide in the presence or absence of a (lower)alkyl, alkenyl or aralkyl halide in an inert solvent while controlling the temperature of reaction in the range of -30 DEG C. to +30 DEG C., drowning the polymerization mixture in water, separating the organic phase therefrom, removing the solvent therefrom and recovering a solid polymer in good yield.
