Publication number: 20090234046Abstract: The invention relates to a copolymer, said copolymer consisting of, as structural units, (i) 0.1 to 50 mole % of units derived from an ethylenically unsaturated monomer (a) having per one mole thereof 25 to 300 moles of C2-C3 oxyalkylene groups; (ii) 0.1 to 49.9 mole % of units derived from a monomer (b) of an alkyl, alkenyl or hydroxyalkyl ester of an ethylenically unsaturated mono- or di-carboxylic acid; (iii) 0.1 to 90 mole % units derived from a monomer (c) selected from the group consisting of an ethylenically unsaturated monocarboxylic acid, a salt thereof, an ethylenically unsaturated dicarboxylic acid, an anhydride thereof and a salt thereof; (iv) optionally up to 30 mole % of other monomers. Said copolymer can be used as a concrete and/or mortar admixture that allows optimal flow ability and, at the same time, can maintain a specific consistency, fluidity and workability of the concrete independently of the cement type.Type: ApplicationFiled: April 27, 2006Publication date: September 17, 2009Inventors: Tatsuo Izumi, Carsten Zanders, Marion Jansen-Bockting, Stefan Dikty

Publication number: 20090221781Abstract: A method of making an aliphatic polyester prepolymer, comprising: reacting, alone or in combination with other reactants, a diol with at least a first diacid (or a diester of said first diacid) to produce an aliphatic polyester prepolymer. The first diacid is preferably a trans-beta-hydromuconic acid (HMA). In some embodiments, the diol contains at least one ether linkage. In some embodiments the diol is further reacted with at a second diacid, or a diester of said second diacid, wherein said second diacid is different from said first diacid. Prepolymers produced from such processes and articles formed therefrom are also described.Type: ApplicationFiled: March 5, 2007Publication date: September 3, 2009Inventors: Valerie Ashby, David Olson

Publication number: 20090176087Abstract: The present invention relates to a recording fabric comprising a substrate layer, and an ink receiving layer formed on one or both surfaces of the substrate layer and containing glycol-modified polyethylene terephthalate, and a manufacturing method of the recording fabric. A recording fabric according to the present invention does not require an additional printing layer and is excellent in chemical properties, mechanical properties and flatness, thereby preventing a spreading or breaking phenomenon of the recording fabric from occurring when using the recording fabric. Furthermore, a recording fabric according to the present invention is characterized in that the recording fabric does not emit endocrine disruptor and harmful gases during use, incineration or fire.Type: ApplicationFiled: December 19, 2008Publication date: July 9, 2009Applicant: LG CHEM, LTD.Inventor: Chan-Oh Yoon
