摘要： 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.

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. The highly branched or dendritic saturated hydrocarbon polymers of the present invention 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. An additional benefit is that the mechanical properties of the polyolefinic film, sheet, pipe or fiber produced with minor amounts of highly branched or dendritic saturated hydrocarbon polymers of the present disclosure are not negatively impacted.
