Patent number: 6458438Abstract: An article of manufacture includes an oxygen scavenger and a zeolite. The article can be in the form of e.g. a film or sealing compound. A package can be made from the article for containing an oxygen-sensitive article such as food. The zeolite reduces migration of odor causing by-products of the oxygen scavenging process. A method of making an article of manufacture having reduced migration of by-products of an oxygen scavenging reaction includes providing an article including an oxygen scavenger and a zeolite; and exposing the article to actinic radiation.Type: GrantFiled: July 31, 2001Date of Patent: October 1, 2002Assignee: Cryovac, Inc.Inventors: Thomas A. Blinka, Frank B. Edwards, Nathanael R. Miranda, Drew V. Speer, Jeffrey A. Thomas

Patent number: 5583047Abstract: A method of detecting the permeability of an article to oxygen is disclosed. A fluorescent redox indicator, preferably riboflavin, is dispersed in a carrier and placed on an impermeable substrate. The article to be measured is placed adjacent to the carrier. Residual oxygen is removed, the redox indicator is photoreduced, the article and carrier are exposed to oxygen, and the indicator is exposed to UV light.Type: GrantFiled: April 22, 1994Date of Patent: December 10, 1996Assignee: W. R. Grace & Co.-Conn.Inventors: Thomas A. Blinka, Christopher Bull, Charles R. Barmore, Drew V. Speer

Patent number: 5042992Abstract: A novel class of polyimides useful in making semipermeable membranes for gas separation is synthesized by the reaction of 4,4'-[hexafluoroisopropylidene]-bis-[phthalic anhydride] (6FDA) with 3,7-diamino-2,8-dimethyldiphenylenesulfone (AMPS). In lieu of the two methyl groups the diamine may be substituted by H or C.sub.2-4 alkyl. Membranes made from the polyimides have high permeability for CO.sub.2 from mixtures containing CO.sub.2 and other gases such as CH.sub.4 and have commercially acceptable selectivity.Type: GrantFiled: March 21, 1990Date of Patent: August 27, 1991Assignee: W. R. Grace & Co.-Conn.Inventors: Thomas A. Blinka, Hiroshi Itatani, I-Fan Wang

Patent number: 4963266Abstract: Disclosed are semipermeable fluid separation membranes prepared from polyaromatic polymers including aromatic repeat units of which at least five mole percent are substituted by moieties having ethylenically unsaturated carbon bonds wherein the polymer is crosslinked through carbon bonds between the ethylenically unsaturated moieties. The invented membranes have enhanced durability yet retain very high fluid, especially gas, permeability.Type: GrantFiled: October 13, 1989Date of Patent: October 16, 1990Assignee: W. R. Grace & Co.-Conn.Inventors: Charles R. Morgan, Cheng-Chi Chen, Thomas A. Blinka, Alan S. Obligin
