    Abstract: The present invention relates to a method to produce highly branched polymers with a polyolefin backbone structure of ethylene and precise control of the nature of the branching. In particular, the distribution of branch length and number of branches can be more precisely controlled via the polymerization method of the present invention. The method comprises using anionic chemistry to make unsaturated polydienes with a well-defined, highly-branched structure, and then hydrogenating these polydienes to form highly branched or dendritic saturated hydrocarbon polymers. Highly branched or dendritic polyethylene, ethylene-propylene copolymer and atactic polypropylene are among the saturated hydrocarbon polymers that can be anionically synthesized via the proper selection of diene monomer type, coupling agent, and hydrogenation conditions. These polymers find application in injection molding and extrusion processes as a minor additive for improving processability of linear polyolefins by delaying the onset of melt fracture, and correspondingly increasing melt throughput rates.

    Abstract: A polyolefin polymer comprising one or more terminal polymerizable methacryloyl groups (i.e. tethered to the main body of the polymer) and a novel process for preparing same are herein disclosed. A hyperbranched polyethylene polymer and a process for preparing same are also disclosed. The polymer is prepared by a novel one-pot copolymerization reaction of an olefin, such as ethylene, and a heterobifunctional comonomer comprising a methacryloyl group, catalyzed by a late transition metal α-diimine catalyst which is selectively non-reactive towards methacryloyl groups. The process allows for preparation of polymers with various chain topologies, including linear, branched, and hyperbranched topologies. The terminal methacryloyl groups within the polymer are reactive in further polymerization reactions. Thus, the polymer may be used in materials and applications which require cross-linking or further polymerization, for example, UV/thermal/radical curable crosslinkers for use in thermoset applications.

    Abstract: A one-pot polymerization process of preparing long chain branching polymers is provided. Also described is a “T” reagent that serves as a link between main and side chains of an inventive long chain branching polymer. A “T” reagent has at least two functionalities, serving as both co-monomer and chain transfer reaction agent. Optionally, a copolymerization reaction between an alpha-olefin and “T” reagent takes place initially to incorporate some “T” molecules in the polyolefin main chain, and the incorporated “T” units then behave as chain transfer agents for reacting with the propagating polyolefin chains to form side chains. In a particular embodiment, a polymerization process for preparing long chain branching polyethylene (LCBPE) and long chain branching polypropylene (LCBPP) is detailed.
