Patents by Inventor Georgy Viktorovich Nesyn

Georgy Viktorovich Nesyn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for producing a suspension-type drag reducing additive for hydrocarbon liquids
    Patent number: 9074024
    Abstract: The invention produces suspensions of higher ?-olefins without using cryogenic comminution as well as without using polymer precipitation by adding a non-solvent to a polymer solution. Fine polymer dispersions are produced by thermal re-precipitation of a polymer in a liquid being a non-solvent for that polymer at room temperature and being capable of dissolving the polymer at a higher temperature. The polymer component of a suspension is produced by co-polymerization of higher ?-olefins in a monomer mass in the presence of a Ziegler-Natta catalyst.

  • Catalyst system and processes for the (co-) trimerization of olefins and the (co-) polymerization of olefin oligomers
    Patent number: 8921251
    Abstract: The invention relates to the field of producing polymers and copolymers of olefin oligomers produced by a trimerization reaction of olefin monomers. There is disclosed a process which comprises producing olefin oligomers with the aid of a trimerization catalyst system prepared using UHF irradiation for activating individual components of the trimerization catalyst system. The use of the trimerization catalyst system thus improved and having increased activity provides for increased effectiveness in the production of olefin oligomers from ethylene or other olefin monomers, inter alia, at a low pressure of ethylene. The olefin oligomers thus produced are then polymerized or copolymerized using processes known in the art. The technical effect consists in increasing the effectiveness of the production of olefin oligomers which are then used in a polymerization or copolymerization reaction.
