According to said method, a stabilizing agent is added to the fluorinated polymer. Said stabilizing agent can be an antioxidant, a graftable metal salt, or a combination of the two. The invention also relates to structures comprising at least one layer of said mixtures and at least one layer of another material, and to the use of said structures to obtain a barrier effect.Type: GrantFiled: December 28, 2004Date of Patent: February 28, 2012Assignee: Arkema FranceInventors: Anthony Bonnet, Fabrice Chopinez, Pascal Sebire, Karine Triballier, Michael Werth, Michaela Steng

Patent number: 8119702Abstract: The present invention provides a resin composition consisting of a functionalized polypropylene (PP) and a functionalized styrenic thermoplastic elastomer (TPS). The functionalized PP is a PP grafted with N-vinyl pyrrolidone (NVP) and glycidyl methacrylate (GMA), and the functionalized TPS is a TPS grafted with acrylamide or methacrylamide. The functionalized PP and the functionalized TPS are subjected to melt blending to obtain the resin composition with a slight cross-linking structure due to the reaction between GMA and acrylamide or methacrylamide, therefore the resin composition presents good physical properties. Besides, the resin composition without additional plasticizer or other small molecular organic compounds can be utilized in blood bags, blood transfusion and collection apparatuses, etc. Thus, it does not release small molecular substances which are of potential harm to human body during use.Type: GrantFiled: September 27, 2010Date of Patent: February 21, 2012Assignee: Changchun Institute of Applied Chemistry Chinese Academy of SciencesInventors: Shifang Luan, Jinghua Yin, Zhongzhi Li, Jianwei Wang, E Zhang, Huawei Yang

Patent number: 8110612Abstract: A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder is described. The process in accordance with one aspect of the invention includes introducing primary raw materials including a non-thermoplastic elastomer into a feeding section of the modified planetary roller extruder, conveying the raw materials from the feeding section to a compounding section of the modified planetary roller extruder, continuously mixing the primary raw materials in the compounding section to produce a homogeneous adhesive composition. The adhesive composition may be applied to a web-form material. The compounding section of the modified planetary roller extruder includes a main spindle surrounded by and intermeshed with a plurality of planetary spindles at least one of which is a double transversal mixing spindle having a plurality of back-cut helical flights.Type: GrantFiled: February 5, 2007Date of Patent: February 7, 2012Assignee: Intertape Polymer Corp.Inventors: John Kinch Tynan, Jr., Richard Walter St. Coeur, David Michael Kovach, Thomas Lombardo
