Publication number: 20110308753Abstract: A continuous filler treatment process has been developed to enhance the fixation of anionic latex on filler in a short time. In this process anionic polymer dispersions (latex) are added to common papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (Tg) of the latex used. To efficiently fix the latex the temperature of the filler/latex mixture must be 30-60° C. higher than the Tg of the latex used. The chemical composition of the resin and the type of surfactant used during the emulsion polymerisation process of the polymer latex dispersions are important factors for efficiently fixing the latex onto the filler by adding hot water and improving the properties of paper made with the treated filler. The enhanced fixation of anionic latex onto filler using hot water is done in mixing vessels that can control shear and mixing time.Type: ApplicationFiled: August 30, 2011Publication date: December 22, 2011Inventors: Makhlouf Laleg, Roderick Collins, Danielle Gagne, Steven Middleton

Publication number: 20110272640Abstract: A method of incorporating an additive into a polyamide-poly(arylene ether) composition includes the step of melt blending a polyamide, a poly(arylene ether), and a dispersion comprising a liquid carrier, an unmodified clay, and an additive. Using the dispersion rather than a polymer-based additive masterbatch saves energy. Like a polymer-based masterbatch, the dispersion provides the additive in a diluted form and therefore preserves the masterbatch's advantages of providing more uniform distribution additive in the plastic and avoiding direct handling of additives in the final compounding step.Type: ApplicationFiled: May 4, 2010Publication date: November 10, 2011Inventors: Jos Bastiaens, Arno Hagenaars

Patent number: 8053497Abstract: The invention concerns the polymers obtained by the use of sulfur compounds in a process for controlled radical polymerization in water of acrylic acid and/or acrylic acid with hydrosoluble monomers. It concerns also their uses as dispersant agents or agents to aid grinding and/or co-grinding of mineral matters in aqueous suspensions, and as dispersant agents incorporated directly in aqueous formulations containing mineral matters. Finally, the invention concerns the formulations of mineral matters obtained in this manner.Type: GrantFiled: October 21, 2010Date of Patent: November 8, 2011Assignee: Coatex S.A.S.Inventors: Jean-Marc Suau, Christian Jacquemet

Publication number: 20110256189Abstract: A coating material for a solid formulation is capable of stably retaining the effective ingredient in the solid formulation for a prolonged period even in unpacked condition in such a manner that the solid formulation can be used in a single-dose formulation. The coating material for a solid formulation includes a high hydrogen-bonding resin and a swelling clay and, when coated on a solid formulation and dried, forms a coating film in which the laminated structures of the aforementioned swelling clay are oriented planarly and dispersed in a network fashion.Type: ApplicationFiled: December 25, 2009Publication date: October 20, 2011Applicant: TORAY INDUSTRIES, INC.Inventors: Yuki Hayashi, Yuki Fujisaki, Ryoji Yoshii

Publication number: 20110236705Abstract: A mixture of a high molecular weight EPDM rubber with a low molecular weight (liquid) EPDM rubber provides a highly useful laser-ablatable flexographic printing plate precursor formulation. This formulation is sensitive to infrared radiation by the incorporation of an IR absorbing compound such as a carbon black. The inclusion of the liquid EPDM rubber avoids the need for plasticizers such as process oils during manufacturing, and provides improved image sensitivity, print quality, and run length. Both flexographic printing plates and printing sleeves can be made using the mixture of EPDM rubbers.Type: ApplicationFiled: March 29, 2010Publication date: September 29, 2011Inventors: Ophira Melamed, Ido Gal, Limor Dahan
