  • Patent number: 10414878
    Abstract: Solid-state shear pulverization of semi-crystalline polymers and copolymers thereof and related methods for enhanced crystallization kinetics and physical/mechanical properties.
    Type: Grant
    Filed: January 22, 2018
    Date of Patent: September 17, 2019

    Inventors: John M. Torkelson, Cynthia Pierre, Amanda Flores Walker, Philip J. Brunner
  • Patent number: 10191371
    Abstract: A method of forming a pattern comprises diffusing an acid, generated by irradiating a portion of a photosensitive layer, into an underlayer comprising an acid sensitive copolymer comprising an acid decomposable group and an attachment group, to form an interpolymer crosslink and/or covalently bonded to the surface of the substrate. Diffusing comprises heating the underlayer and photosensitive layer. The acid sensitive group reacts with the diffused acid to form a polar region at the surface, in the shape of the pattern. The photosensitive layer is removed to forming a self-assembling layer comprising a block copolymer having a block with an affinity for the polar region, and a block having less affinity than the first. The first block forms a domain aligned to the polar region, and the second block forms a domain aligned to the first. Removing either the first or second domain exposes a portion of the underlayer.

  • Patent number: 10179885
    Abstract: A dispersant includes the reaction product of an amine and at least one equivalent of glycidyl ether where the amine is selected from a group consisting of aminoethylpiperazine, bis(2-(piperazin-1-yl)ethyl)amine, 4,4?-methylenebiscyclohexylamine, m-xylenediamine, diethylenetriamine, and triethylenetetramine and where the glycidyl ether has the structure (A), where R is selected from aromatic carbon chains, non-aromatic carbon chains and polyalkylene glycol groups. The dispersant is useful in a lubricant with a base oil for increasing soot dispersibility of the lubricant.
