Patent number: 8188185Abstract: A biodegradable packaging film is provided. The film is formed from a blend that contains a thermoplastic starch and polylactic acid. Starch is a relatively inexpensive natural polymer that is also renewable and biodegradable. Polylactic acid is likewise an inexpensive synthetic polymer that is biodegradable and renewable, yet also capable of providing increased tensile strength to the film. Although providing a good combination of biodegradability/renewability and increased tensile strength, the polylactic acid is also relatively rigid and can result in films having a relatively high stiffness (e.g., high modulus of elasticity) and low ductility. While more ductile than polylactic acid, the thermoplastic starch is often difficult to melt process in film forming processes and very sensitive to moisture and water vapor, reducing its ability to be used as a stand alone packaging film.Type: GrantFiled: June 30, 2008Date of Patent: May 29, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James H.

Publication number: 20110105638Abstract: An end-modified soluble polyfunctional vinyl aromatic copolymer, which is improved in heat resistance, thermal stability, solvent solubility, and compatibility with acrylate compounds, and a curable resin composition using the same are disclosed. The end-modified soluble polyfunctional vinyl aromatic copolymer is obtained by allowing a divinyl aromatic compound (a), a monovinyl aromatic compound (b), and an aromatic ether compound (c) to react with each other, and has, at an end, an end group derived from the aromatic ether compound and having an acrylate bond. The copolymer has a number average molecular weight Mn of 500 to 100,000, an introduction amount (c1) of the end group derived from the aromatic ether compound satisfies (c1)?1.0 (group/molecule), a molar fraction a? of a structural unit derived from the divinyl aromatic compound and a molar fraction b? of a structural unit derived from the monovinyl aromatic compound in the copolymer satisfy 0.05?a?/(a?+b?)?0.95.Type: ApplicationFiled: March 3, 2009Publication date: May 5, 2011Applicant: Nippon Steel Chemical Co., Ltd.Inventors: Masanao Kawabe, Hiroko Terao, Natsuko Okazaki
