    摘要： The invention is a practical process for anionically synthesizing commercially significant quantities of macrocyclic polymers from polar and/or non-polar monomers by using Group IIA and IIB metal cyclic organometallic initiators. Activation of the ring metal atom results in anionic polymerization of the monomers by addition into the initiator ring at the bonds between the atom and its two adjacent carbon atoms, the metal atom acting as a bridge between the two living ends of the propagating chain. Coupling of the cyclic polymer living ends by coupling agents produces macrocyclic polymers that are stable in air and moisture and that exhibit desirable properties, such as low viscosities at high molecular weights. Such macrocyclic polymers provide enhanced polymer processability during molding, extruding and the forming of films. Macrocyclic polymers terminated with coupling agents that also provide functional groups may be compounded to produce vulcanizable elastomeric compounds and articles that exhibit reduced hysteresis properties.

    摘要： A process is provided for the preparation of tapered copolymers by the nonaqueous dispersion polymerization of a mixture of 30 to 70% by weight of a conjugated diolefin monomer, preferably butadiene, and 30 to 70% by weight of a vinyl substituted aromatic monomer, preferably styrene, in a liquid hydrocarbon dispersion medium with an anionic initiator catalyst system in the presence of a block copolymeric dispersing agent. At least one block of the dispersing agent is prepared prior to the dispersion polymerization reaction and at least one block of the dispersing agent is prepared in situ during the dispersion copolymerization. The block of the dispersing agent that is prepared in situ has the polymer structure of the tapered copolymer.
