    • Conjugated diolefinic polymers having a molecular weight of less than 1,000,000 can be produced at high polymerization rates and in high yields by polymerizing a conjugated diolefin or copolymerizing a conjugated diolefin with a vinyl aromatic hydrocarbon in the presence of an alfin catalyst, in which as a molecular weight regulator is used a halogenated unsaturated hydrocarbon represented by the formula, ##EQU1## wherein R is an alkyl group having 1 to 7 carbon atoms, a vinyl group, a phenyl group, an alkyl-substituted phenyl group, a halogen atom or a hydrogen atom, and X, Y and Z which may be same or different are individually a hydrogen atom, a halogen atom or an alkyl group having 1 to 4 carbon atoms, at least one of the R, X, Y and Z being a halogen atom. The above-mentioned molecular weight regulator not only displays a prominent molecular weight-regulating effect, even when used in a small amount, but also is easily commercially obtainable and inexpensive, so that marked commercial advantages can be attained according to the above-mentioned process.

    • A process for manufacturing a cycloolefin addition polymer includes polymerizing monomers containing a cycloolefin compound using a catalyst containing a nickel compound or a palladium compound by addition polymerization in the presence of a molecular weight controlling agent in two steps, that is a step of a initiating the polymerization reaction using the monomers in an amount of not more than 80 wt % of the total monomers and a step of supplying the remaining monomers to the reaction system during the polymerization reaction. A cycloolefin addition polymer with a uniform quality, having a narrow molecular weight distribution and a controlled molecular weight, and excellently balanced processability and mechanical strength can be obtained at a high polymerization conversion rate using the process. The process can be operated at a highly controlled polymerization temperature, and is thus suitable for industrially manufacturing a cycloolefin addition polymer.
