Claim 3
Dependent Claim
106 words
A POLYMERIZATION PROCESS WHICH COMPRISES MIXING 60 TO 95 PARTS OF A CONJUGATED DIOLEFIN AND 40 TO 5 PARTS OF MYRCENE, 50 TO 500 PARTS OF AN INERT HYDROCARBON DILUENT BOILING BETWEEN -15%C. AND 250*C., 10 TO 50 PARTS OF A PROMOTER SELECTED FROM THEGROUP CONSISTING OF OPEN-CHAIN ETHERS HAVING 4 TO 8 CARBON ATOMS AND CYCLIC DI-ETHERS HAVING 4 TO 8 CARBON ATOMS WHEREIN THE TWO OXYGEN ATOMS ARE SEPARATED BY AT LEAST TWO CARBON ATOMS, AND 1.0 TO 5 PARTS OF A FINELY DIVIDED ALKALI METAL, AND MAINTAINING THE RESULTING MIXTURE AT A TEMPERATURE BETWEEN 25 AND 105*C. UNTIL SUBSTANTIALLY 100% CONVERSION IS OBTAINED.
