    Abstract: The method of making polyolefin with a silicon nitride nano-filler uses silicon nitride (SiN) as a promoter for in situ polymerization with a zirconocene catalyst. The method includes adding the bis(cyclopentadienyl) zirconium dichloride catalyst and nanoparticles of silicon nitride to a reactor. The reactor is then charged with toluene and a methylaluminoxane co-catalyst, and is heated for a period of time sufficient to bring the reactor to a polymerization reaction temperature. Nitrogen gas is removed from the reactor following the heating, and then ethylene monomer is fed into the reactor, initiating polymerization. The polymerization is then quenched, and non-reacted monomer is vented. The polyolefin product is then removed from the reactor, washed and dried.

  • Patent number: 8642711
    Abstract: Provided is a low-cost, highly active, environmentally friendly living radical polymerization method which does not require a radical initiator. Even if a catalyst is not used, a living radical polymerization method can be conducted by controlling the amount of the oxygen in the gaseous phase in the reaction vessel within a suitable range. A monomer having a radical-reactive unsaturated bond can be subjected to a radical polymerization reaction to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced. The present invention eliminates the disadvantages of the conventional catalysts such as toxicity, low solubility, coloring/odor and the like, and is significantly more environmentally friendly and economically efficient than conventional living radical polymerization methods.

  • Patent number: 8338550
    Abstract: A ring-opening metathesis polymerization (ROMP) reaction is disclosed in which a cyclic alkene compound is subjected to ROMP using a ruthenium ROMP catalyst having heterocyclic ligands in the presence of a compound from which such ligands may be derived. The process includes the step of adding sufficient of an acyclic alkene having a carbon-carbon double bond capable of reacting with the catalytic metal moieties attached to the living end of each of the polymer chains generated in the ROMP reaction to end cap the polymer chains and to generate a olefin metathesis catalyst. The process includes reiterating the polymerization steps by adding further amounts of a cyclic alkene compound. The catalyst may be generated in situ from a precursor compound by the addition of a compound from which heterocyclic ligands may be derived by interaction with the precursor compound.

  • Patent number: 8273823
    Abstract: The invention is directed to a microemulsion polymerization comprising adding a polymerization catalyst precursor, such as a transition metal complex in the higher of two accessible oxidation states, an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion. Radically polymerizable monomers and a reducing agent may then be added to the emulsion. The reducing agent converts the catalyst precursor to a catalyst for polymerization of the first monomer from the initiator. In certain embodiments the organic solvent may comprise radically polymerizable monomers. The aqueous solution may comprise a surfactant.

  • Patent number: 8178465
    Abstract: The disclosure provides for a process and polymerization system to produce isoolefin polymers (72) utilizing polymorphogenates (16, 26) in the catalyst system to control polydispersity (MWD). The disclosure also provides a catalyst system (20) comprising a plurality of active catalyst complex species (34) formed by combination of a Lewis acid (24), an initiator (22) and a polymorphogenate (26), as well as polymers made using the catalyst system or process. The polymorphogenate (16, 26) can promote or mimic the formation of different active catalyst complex species (34) having different polymerization rates, i.e. different rates of propagation, chain transfer, or termination, as observed by different polydispersities resulting from the presence of relatively different proportions of the polymorphogenate.
