Patent number: 7960496Abstract: Disclosed herein is a novel stabilizer for preparing a polymer polyol, which is used to prepare polyurethane foam having improved physical properties. The stabilizer is prepared by allowing maleic anhydride to react with a polyether polyol, having an OH functionality of 3-8 and a molecular weight of 3,000-15,000, and then adding ethylene oxide to the reaction solution. Because the molecular weight and functionality of the stabilizer are increased through aging and dimerization, the stabilizer has a high molecular weight of 5,000-30,000, a high OH functionality of 6-10 and a viscosity of 3,000-15,000 cps/25° C. A polymer polyol derived from the stabilizer has low viscosity compared to those of prior products and contributes to the improvement in the physical properties of the resulting polyurethane foam.Type: GrantFiled: December 14, 2007Date of Patent: June 14, 2011Assignee: Korea Kumho Petrochemical Co., Ltd.Inventors: Jang Hyun Choi, Seung Moo Huh, Jeon Koo Lee, Jong Yeol Choi

Publication number: 20110020660Abstract: The invention relates to a biodegradable polyester, particularly suitable for extrusion coating, comprising units deriving from at least a diacid and at least a diol, with long chain branches (isometric with respect to the main chains of the polyester) and essentially gel-free, characterized by optimum adhesion to paper, excellent sealability and processability in extrusion coating systems. Said biodegradable polyester is obtainable through a reactive extrusion process starting from a substantially linear polyester precursor with defined viscosity and concentration of reactive sites which allow transformation of a few chains of the polyester precursor into isometric branches of this polyester. A further object of the present invention is a laminate product composed of at least a backing, preferably paper, and of at least a first layer composed of polyester according to the invention.Type: ApplicationFiled: March 26, 2009Publication date: January 27, 2011Applicant: Novamont S.p.A.Inventors: Catia Bastioli, Angelos Rallis

Publication number: 20100249361Abstract: There is disclosed a process for producing a polyester copolymer. The process comprises the step of condensating a hydroxyacid, a diol, a dicarboxylic acid and a functionalizing agent selected to form a prepolymer having a polyester copolymer backbone with arms comprising cross-linkable groups extending therefrom. The process also comprises the step of coupling said prepolymer in the presence of a coupling agent to cross link the arms of plural prepolymer backbones and thereby form said polyester copolymer comprising said plural straight chain polyester copolymers coupled to each other by said cross-linked arms. The polyester copolymer may be biodegradable and may be used as a modifier to increase the strength of polylactic acid.Type: ApplicationFiled: July 29, 2008Publication date: September 30, 2010Inventors: Shaofeng Wang, Bo Jing, Yuqiang Huang, Lianlong Hou, Siok Ling Sherlyn Yap
