Patent number: 8378001Abstract: 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: GrantFiled: January 29, 2010Date of Patent: February 19, 2013Assignee: Owens Corning Intellectual Capital, LLCInventors: Yadollah Delaviz, Raymond M.

Patent number: 8349909Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an infrared attenuating agent, and a polystyrene/polyethylene oxide copolymer are provided. In exemplary embodiments, the blowing agent contains an HFC. The maleic anhydride-styrene copolymer grafted with polyethylene oxide increases the cell size of the polymer foam and offsets or even negates the decreased cell size caused by an HFC blowing agent and/or infrared attenuating agents. In addition, 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. A method of forming an extruded foam product is also provided.Type: GrantFiled: January 29, 2010Date of Patent: January 8, 2013Assignee: Owens Corning Intellectual Capital, LLCInventors: Yadollah Delaviz, Raymond M.
