Abstract

PURPOSE: To produce a liquid or semisolid low polymer having olefin residue at its terminal, by using an olefin compd. as a chain transfer agent in a process for the polymn. of a conjugated diolefin using an (org.) alkali metal as a catalyst.
CONSTITUTION: An olefin compd. of the formula (wherein R1WR4 are each H, a 1W20C alkyl, aralkyl) sucu as propylene or butene is used as a chain transfer agent. A catalyst [an (org.)alkali metal] in an amount of 0.01W1mol/l based on the whole amount of polymn. mixture and said chain transfer agent in an amount of 3W 100mol per mol of the catalyst, are added to a 4W10C conjugated diolefin (e.g. butadiene). The diolefin is polymerized at 0W150°C to produce the desired polymer having a number-average MW of 200W10,000.
