Publication number: 20110281996Abstract: Chain-extended nanonylon is made from the reaction of in-situ polymerized nanonylon and chain-extending agents. Knowing the viscosity/shear rate curve for a thermoplastic polymer to be replaced, such as nylon, the method of the present invention allows via adjustment of organoclay concentration and chain extension of the nylon polymer and other reaction factors to achieve a chain-extended, in-situ polymerized nanonylon to have a viscosity/shear rate curve that essentially matches the viscosity/shear rate curve for that neat nylon within a commercially operable shear rate.Type: ApplicationFiled: July 26, 2011Publication date: November 17, 2011Applicant: POLYONE CORPORATIONInventor: Joseph C.

Publication number: 20110274907Abstract: Curative fibre components comprise one or more fibres for filaments of curative suitable to cure curable resins such as thermoset resin. In curative fibre components comprising a plurality of fibres of curative, the fibres can be commingled, such as twisting, to form a thread or yarn. Curative fibre components can be used to form a material in the form of a sheet, fabric, layer, textile or mat of woven or non-woven curative fibres. Curative fibre components can be used to produce composite materials such as fibre reinforced resinous composite materials. The curative fibre components can be commingled, including interwoven, stitched and layered with other fibres or fibrous materials, such as fibrous reinforcement, fibrous curable resin, fibrous thermoplastic, other non-reinforcing fibres to form composite materials, prepregs, preforms and articles.Type: ApplicationFiled: November 24, 2009Publication date: November 10, 2011Inventors: Mark Raymond Steele, Andrew Gibbs, Amy Grace Atinkson

Patent number: 8026309Abstract: A process is provided for producing a compatibilized polymeric blend. A first thermoplastic polymer and a reactive moiety are provided to a progressive melt kneading apparatus. The reactive moiety comprises a first reactive group capable of reacting with the first thermoplastic polymer but not a second polymer and a second reactive group capable of reacting with the second polymer but not the first polymer. The first thermoplastic polymer and the reactive moiety are then melt kneaded so that the first reactive group reacts with the first thermoplastic polymer and the second reactive group is grafted to the first thermoplastic polymer, forming a molten self-compatibilizer. A molten second polymer is then provided. The molten self-compatibilizer is melt kneaded with the molten second polymer so that the second reactive group reacts with the second polymer to form a compatibilized polymeric blend. Also provided are articles formed from the compatibilized polymer blend.Type: GrantFiled: February 29, 2008Date of Patent: September 27, 2011Assignee: PRS Mediterranean Ltd.Inventors: Izhar Halahmi, Oded Erez, Adi Erez
