  • Patent number: 10271608
    Abstract: It is desired to teach an open footwear article where the upper surface contacting the foot is partially combined with, or wholly comprised of, a substantially rigid material that has some degree of open porosity. The purpose of said rigid, porous material serves to immediately absorb perspiration and/or water from the feet. Subsequent drying of the porous, rigid material occurs when the sandal is not in use as water/perspiration are evaporated from within the pores. The porous, rigid material also effects a massaging action while walking. It is the intent of this invention to capture a preferred combination of these two embodiments.

    Abstract: A non-skid coating described herein attempts to overcome the deficiencies of the conventional coatings with improved external durability and color retention, a reduced level of VOCs, and direct-to-metal (DTM) adhesion using organo-siloxane chemistry. The non-skid coating has a first component having an amino-functional siloxane resin; a second component having a non-aromatic epoxy resin; a spherical filler for lowering viscosity; a pigment; a coarse aggregate; and a thixotropic agent. The amino-functional siloxane resin can be an amino-functional methyl phenyl polysiloxane, diphenyl polysiloxane or silsesquioxane-based resin. The non-aromatic epoxy resin can be cycloaliphatic or aliphatic. The first component is about 5% to 20% weight of the coating, and the second component is about 80% to 95% weight of the coating.

  • Patent number: 8114921
    Abstract: A macromolecule includes a polymer directly tethered or bonded to a polyatomic functionality. The polyatomic functionality can be located at a terminus of the polymer and can be generated concurrent with or soon after formation of the polymer. The macro-molecule can be prepared from a functionalized polymer by hydrolyzing and condensing (e.g., by a sol-gel process) functionalities in which one or more alkoxy groups are bound to a silica atom in the presence of an excess of a compound that includes a Si, Ti, Zr, Sn, Al, or Fe atom. Such macromolecules can be used in the manufacture of vulcanizates and tire components, either alone or blended with other polymers and/or other particulate fillers.

  • Patent number: 7932346
    Abstract: A novel process is used to prepare synthetic rubbers (B) which feature very narrow molecular weight distribution and a correspondingly low value for the polydispersity index. The preparation process encompasses the treatment of a synthetic rubber with ultrasound, where the resultant synthetic rubber (B) has a lower weight-average molecular weight (Mw) than the synthetic rubber (A) used. The resultant synthetic rubbers (B) have excellent suitability for processing via extruder processes or injection-molding processes.
