Patent number: 10882928Abstract: The present invention includes a process for producing treated filler that includes (a) treating a slurry that includes untreated filler, where the untreated filler has not been previously dried, with a treating composition that includes a treating agent, thereby forming a treated filler slurry, and (b) drying the treated filler slurry to produce treated filler. The treating agent can include a polymer having (i) at least one first group that interacts with the untreated filler and (ii) at least one second group that interacts with a rubber matrix into which the treated filler is incorporated. The present invention also is directed to treated filler prepared by the process, as well as rubber compounding compositions and tires including the treated filler.Type: GrantFiled: June 23, 2017Date of Patent: January 5, 2021Assignee: PPG Industries Ohio, Inc.Inventors: Timothy A. Okel, Peter L. Votruba-Drzal, Justin J. Martin, Raphael O. Kollah, Truman Wilt, Brian K. Rearick, Clint Steven Edelman, Feng Wang, Linda K. Anderson, Kurt G. Olson

Patent number: 9546326Abstract: The present invention is directed to methods of separating a fluid emulsion stream into a hydrocarbon stream and an aqueous stream, by contacting the stream with a microporous membrane to yield a hydrocarbon product stream and an aqueous product stream. The membrane comprises a substantially hydrophobic, polymeric matrix, and substantially hydrophilic, finely divided, particulate, substantially water-insoluble filler distributed throughout the matrix. The polymeric matrix has a mean pore size less than 1.0 micron, and the purities of the product streams are independent of the flux rate of the aqueous product stream and the pore size of the membrane.Type: GrantFiled: February 28, 2014Date of Patent: January 17, 2017Assignee: PPG Industries Ohio, Inc.Inventors: Qunhui Guo, Carol L.

Patent number: 9030740Abstract: Photochromic-dichroic articles are provided, which include a substrate having a first surface, a fixed-polarized layer over the first surface of the substrate, and a photochromic-dichroic layer over the first surface of the substrate. The fixed-polarized layer optionally includes a fixed-colorant and has a first polarization axis. The photochromic-dichroic layer includes a photochromic-dichroic compound that is laterally aligned within the photochromic-dichroic layer, and which defines a second polarization axis. The first polarization axis and the second polarization axis are oriented relative to each other at an angle of greater than 0° and less than or equal to 90°. The photochromic-dichroic articles can provide, for example, increased optical density and/or increased kinetics when exposed to a given amount of actinic radiation.Type: GrantFiled: September 14, 2012Date of Patent: May 12, 2015Assignee: Transitions Optical, Inc.Inventors: Rachel L.

Publication number: 20070071903Abstract: A method of applying a multi-component coating composition to a substrate is disclosed. The coating composition comprises a polymeric component containing reactive functional groups and a hardener component comprising a curing agent having coreactive functional groups. The composition is applied with a spray applicator and the rheological profile of the polymeric component is adjusted by adding to the polymeric component one or more materials having a lower molecular weight than the polymeric component and which contain functional groups reactive with the curing agent such that the polymeric component and the hardener component are delivered to a mixing chamber in the spray gun at a predetermined volume ratio over a varied range of temperatures and shear rates.Type: ApplicationFiled: November 20, 2006Publication date: March 29, 2007Inventors: James Claar, David Walters, Truman Wilt, John Rassau
