Polymerization of α-pinene |
| abstract |
There is provided a process for polymerizing alpha -pinene by adding the same incrementally to a catalyst system comprising a major amount of an aluminum halide and a minor amount of an organo germanium halide or alkoxide in admixture with 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. |
