Publication number: 20130210621Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.Type: ApplicationFiled: February 10, 2012Publication date: August 15, 2013Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A.

Publication number: 20110237691Abstract: A cured porous phenolic resin is provided that can be made by cross-linking a phenol-formaldehyde pre-polymer in the presence of a pore former, preferably ethylene glycol. The resin may be formed in situ by condensing a phenol with or without modifying agents and with cross-linking agent by pouring partially cross-linked resin into hot oil, in which case mesoporous resin beads are obtained. The resulting resin has mesopores observable in carbon derived from said resin by a pore structure of said derived carbon that comprises mesopores of diameter of 20-500 ?, as estimated by nitrogen adsorption porosimentry, the value for the differential of pore volume V with respect to the logarithm of pore radius R (dV/d log R) for the mesopores being greater than 0.2 for at least some values of pore size in the range 20-500 ?. Microporous beads of the resin may be carbonized into mesoporous carbon beads.Type: ApplicationFiled: April 29, 2011Publication date: September 29, 2011Inventors: Stephen Robert TENNISON, Oleksundr Prokopovych KOZYNCHENKO, Volodymyr Vasyljovych STRELKO, Andrew John BLACKBURN

Patent number: 7994229Abstract: The present invention provides a process for producing thermo-expansive microspheres comprising a thermoplastic resinous shell and a blowing agent being encapsulated in the shell, the blowing agent which is a fluorine-containing C2-10 compound having ether linkage, being free of chlorine and bromine atoms and gasifying at a temperature not higher than the softening point of the thermoplastic resin. The thermo-expansive microspheres have preferably an average particle size ranging from 1 to 100 ?m and a CV, or coefficient of variation, of particle size distribution being 30% or less, and a retaining ratio of blowing agent encapsulated being 90% or more.Type: GrantFiled: February 6, 2008Date of Patent: August 9, 2011Assignee: Matsumoto Yushi-Seiyaku Co., Ltd.Inventors: Katsushi Miki, Toshiaki Masuda, Ichiro Takahara, Takashi Fujie, Ikuo Yosejima

Publication number: 20110190405Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, a polystyrene/polyethylene oxide copolymer, and optionally, an infrared attenuating agent, are provided. In exemplary embodiments, the blowing agent includes at least one hydrofluorocarbon blowing agent. The maleic anhydride-styrene copolymer grafted with polyethylene oxide provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid.Type: ApplicationFiled: January 29, 2010Publication date: August 4, 2011Inventors: Yadollah Delaviz, Raymond M.

Publication number: 20110189461Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an additive blend of polyethylene oxide and a copolymer of polystyrene and maleic anhydride, and optionally, an infrared attenuating agent, are provided. In exemplary embodiments, the polyethylene oxide is ethoxylated polyethylene oxide. Additionally, in at least one embodiment, the blowing agent includes at least one hydrofluorocarbon blowing agent. The blend of ethoxylated polyethylene oxide and copolymer of polystyrene and maleic anhydride provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product and increases the average cell size of the foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the additive acts as a cell enlarger, a water vapor permeability enhancer, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.Type: ApplicationFiled: January 29, 2010Publication date: August 4, 2011Inventors: Yadollah Delaviz, Raymond M. Breindel, John F.
