Patent number: 7241832Abstract: Biodegradable polymer blends suitable for laminate coatings, wraps and other packaging materials are manufactured from at least one “hard” biopolymer and at least one “soft” biopolymer. “Hard” biopolymers tend to be more brittle and rigid and typically have a glass transition temperature greater than about 10° C. “Soft” biopolymers tend to be more flexible and pliable and typically have a glass transition temperature less than about 0° C. While hard and soft polymers each possess certain intrinsic benefits, certain blends of hard and soft polymers have been discovered which possess synergistic properties superior to those of either hard or soft polymers by themselves. Biodegradable polymers include polyesters, polyesteramides, polyesterurethanes, thermoplastic starch, and other natural polymers. The polymer blends may optionally include an inorganic filler. Films and sheets made from the polymer blends may be textured so as to increase the bulk hand feel.Type: GrantFiled: March 1, 2002Date of Patent: July 10, 2007Assignee: bio-tec Biologische Naturverpackungen GmbH & Co., KGInventors: Kishan Khemani, Harald Schmidt, Simon K.

Patent number: 7067611Abstract: Polyhydroxycarhoxylic acids are provided, which are controlled in terms of the rate of biodegradability, and give molded or otherwise formed articles that are of uniform quality with neither premature strength drop nor premature deterioration of retention of outside shape, and their production process is provided as well. The poly-hydroxycarboxylic acids are obtained by ring-opening polymerization of cyclic esters. The polyhydroxy-carboxylic acids have a weight-average molecular weight (Mw) in the range of 10,000 to 1,000,000, a molecular weight distribution in the range of 1.0 to 2.5 as represented by the weight-average molecular weight-to-number-average molecular weight ratio (Mw/Mn) and a yellowness index (YI) of 40 or less, and have a precisely controlled rate of biodegradability.Type: GrantFiled: July 5, 2002Date of Patent: June 27, 2006Assignee: Kureha CorporationInventors: Kazuyuki Yamane, Yukichika Kawakami

Patent number: 6841604Abstract: A polyester with a carbon black content of up to 20% by weight, based on the polyester, is condensed, after transesterification of DMT with diol, or after esterification of terephthalic acid with diol, with the aid of a titanium-based catalyst. The carbon black is added in the form of a carbon black dispersion together with the polycondensation catalyst to the transesterification product or esterification product. The carbon black dispersion comprises gas black or furnace black and a dispersing agent, and these are dispersed in diol. The diameter of the carbon black particles is below that of carbon black particles in a polyester using an antimony compound as catalyst.Type: GrantFiled: November 15, 2002Date of Patent: January 11, 2005Assignee: INVISTA Technologies, S.a. r.l.Inventors: Uwe Bayer, Jürgen Popp, Thomas Wehrmeister

Patent number: 6827882Abstract: Provided is a non-halogen, flame-retardant polycarbonate resin composition that comprises a resin mixture of (A) from 60 to 99% by mass of a polycarbonate resin and (B) from 1 to 40% by mass of a polycarbonate copolymer having phosphorus atoms in its main chain, and contains (C) from 0.02 to 5 parts by mass, relative to 100 parts by mass of the resin mixture, of an anti-dripping agent. Also provided are moldings of the composition. The polycarbonate copolymer (B) that has phosphorus atoms in its main chain is typically a polycarbonate copolymer of which the repetitive structural units contain an aromatic organophosphate component. The resin moldings have good impact resistance, good heat resistance and high stiffness intrinsic to polycarbonate resin. Not depositing on the wall of molds, the melt of the resin composition is well flowable and is stably molded into high-quality moldings having good appearance, and its long-run workability is good.Type: GrantFiled: June 12, 2001Date of Patent: December 7, 2004Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Masahiro Kitayama, Toshio Isozaki, Akio Nodera
