  • Patent number: 4098982
    Abstract: There is provided a process for cationically polymerizing piperylene batchwise or continuously by the addition of piperylene either alone or in admixture with a minor amount of at least another hydrocarbon monomer, incrementally, to a catalyst system consisting essentially of a major amount of an aluminum halide and a minor amount of an inorganic phosphorus acid in an inert solvent while controlling the temperature of reaction in the range of 0.degree. C. to 50.degree. C., drowning the polymerization mixture in water, separating the organic phase therefrom, then removing the solvent and recovering a solid polymer in good color and yield, free from an intractable gel, rendering the same useful as a tackifying resin.
    Type: Grant
    Filed: March 8, 1977
    Date of Patent: July 4, 1978
    Assignee: Arizona Chemical Company
    Inventor: Ronald Thomas Wojcik
  • Patent number: 4048095
    Abstract: 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.degree. C. to +30.degree. C., drowning the polymerization mixture in water, separating the organic phase therefrom, removing the solvent therefrom and recovering a solid polymer in good yield.
