Kshitij Kishen Parab 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).

  • Patent number: 11021617
    Abstract: The disclosure relates to polymers including one or more 1,1-disubstitued alkene monomers. By employing a plurality of monomers and/or tailored chain structure, polymers having improved combinations of properties are achieved. The polymer may be a copolymer, preferably including two or more 1,1-disubstituted alkene monomers. The polymer may be a homopolymer having a tailored chain structure.
    Type: Grant
    Filed: April 11, 2019
    Date of Patent: June 1, 2021
    Assignee: Sirrus, Inc.
    Inventors: Jeffrey M. Sullivan, Aniruddha Palsule, Alexander R. Holzer, Peter Rulon Stevenson, Kshitij Kishen Parab
  • Publication number: 20200223779
    Abstract: The present teachings disclose contacting an amine salt catalyst with a dicarbonyl compound having an alkylene group between the carbonyl group; adding formaldehyde, paraformaldehyde, or formalin in an amount of about 2:1 to about 3:1 moles of formaldehyde to moles of the dicarbonyl compound to form a mixture; and refluxing the mixture. The process forms a carbonyl-substituted alkene. The process may be performed in the absence of a solvent. The process may form methylene malonates, methylene dimalonates, methylene keto malonamides, methylene diketones, methylene keto esters, and the like.

  • Patent number: 10167348
    Abstract: The present teachings show that it is possible to polymerize 1,1-disubstituted alkene compounds in a solution (for example using one or more solvents). Polymerization of 1,1-disubstituted alkene compounds in a solution provides opportunities to better control the polymerization compared with bulk polymerization. The solution polymerization techniques can be employed for preparing homopolymers, copolymers (e.g., random copolymers), and block copolymers.

  • Patent number: 9938223
    Abstract: Disclosed are methods for the catalytic transesterification of compounds having one or more ester groups and groups reactive under transesterification conditions, such as 1,1-disubstituted alkene compounds, with alcohols or esters and novel compositions prepared therefrom. Further disclosed are novel compounds and compositions prepared as a result of the methods.
