Patent number: 5569737Abstract: A process for making polyetheresters is disclosed. A polyether is reacted with a carboxylic acid in the presence of a strong protic acid or a metal salt of a strong protic acid to promote insertion of the carboxylic acid into polyether carbon-oxygen bonds to produce a polyetherester. The polyetheresters are useful for various applications in the polyurethane and unsaturated polyester industries.Type: GrantFiled: April 10, 1995Date of Patent: October 29, 1996Assignee: Arco Chemical Technology, L.P.Inventors: Lau S. Yang, Jeffrey A. Klang

Patent number: 5536760Abstract: Disclosed is a liquid, radiation curable composition comprising: (A) an unsaturated polyester component containing an unsaturated polyester polymer, an unsaturated polyester oligomer or a mixture thereof; and (B) a non-polymerized, cocurable vinyl ether component which may be separate from or structurally incorporated in the unsaturated polyester component, provided that the vinyl ether component contains an average of at least two vinyl ether groups per molecule of the vinyl ether component.Also disclosed is a method of coating comprising: applying to a substrate a film of a liquid, radiation curable composition of the invention, and curing the composition through its thickness to a tack-free state by exposing the film to ionizing radiation and/or ultraviolet light.Type: GrantFiled: December 10, 1993Date of Patent: July 16, 1996Assignee: PPG Industries, Inc.Inventors: Charles B. Friedlander, David A. Diehl

Patent number: RE38928Abstract: A biaxially stretched polyester film for forming a container, characterized by being formed of a polyester substantially consisting of an ethylene terephthalate unit and an ethylene naphthalate unit, the refractive index in the direction of thickness of the film being 1.5 or greater. This film is not only excellent in the formability during formation into cans or the like, but has excellent properties in taste property, particularly, the taste property after the retorting, and may be suitably used for containers produced by forming process and, particularly, for metallic cans.Type: GrantFiled: May 15, 1997Date of Patent: January 3, 2006Assignee: Toray Industries, Inc.Inventors: Masahiro Kimura, Kohzo Takahashi, Hiroji Kojima, Koichi Abe
