ABSTRACT OF THE DISCLOSURE There is provided a process for cationally polymer- izing or co-polymerizing batchwise or continuously .alpha.-pinene by adding .alpha.-pinene either alone or in admixture with other ter- pene 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 in- ert solvent while controlling the temperature of reaction in the range of -30°C. to +30°C., drowning the polymerization mixture in water, separating the organic phase therefrom, re- moving the solvent therefrom and recovering a solid polymer in good yield.
