Claims
- 1. Process for the preparation of a soluble polycyclic polyene polymer having residual unsaturation and high molecular weight wherein at least one monomer is 1-isopropylidendicyclopentadiene, said momomer being reacted in the presence of a catalyst system of the cationic type consisting of a halide of an element of the second to the eighth groups of the periodic table or a water alcohol, acid, ether or alkyl halide complex thereof that is selected from the group consisting of BF.sub.3. OEt, TiCl.sub.4, Et2Alcl and EtAlCl.sub.2 to form said polycyclic polyene polymer.
- 2. Process according to claim 1 wherein the reaction is carried out at a temperature in the range between -100.degree. and +20.degree. C.
- 3. Process according to claim 1 wherein the reaction is carried out in the presence of a solvent selected from the group consisting of aromatic, aliphatic, cycloaliphatic and chlorinated hydrocarbons.
- 4. A process as defined in claim 1 wherein the halide of an element of the second to the eighth groups of the periodic table is BF.sub.3 -OEt.
- 5. A process as defined in claim 1 wherein the halide of an element of the second to the eighth groups of the periodic table is TlCl.sub.4.
- 6. A process as defined in claim 1 wherein the halide of an element of the second to the eighth groups of the periodic table is Et.sub.2 AlCl.
- 7. A process as defined in claim 1 wherein the halide of an element of the second to the eighth groups of the periodic table is EtAlCl.sub.2.
