Patent number: 5858529Abstract: Polyester staple fibers with high resistance to pilling contain (1) a polyester component consisting of at least 90 mol % polyethylene terephthalate, after its polycondensation, and (2) 1 to 7% by weight, relative to the polyester component, of a polyalkylene glycol block polymer with the formula ##STR1## in which the polyoxypropylene core has a mean molecular weight of 3000 to 4000 and a, b and c are integers such that the polyoxyethylene groups form 20 to 60% by weight of the block polymer, which has a mean molecular weight of 3750 to 10000. The staple fibers are prepared by admixing the polyester component and the block copolymer evenly in a separate phase and spinning the two together in the usual manner. The polyester component preferably is polyethylene terephthalate homopolyester, to which 2-4% by weight of the block copolymer is admixed.Type: GrantFiled: November 13, 1997Date of Patent: January 12, 1999Assignee: Akzo Nobel NVInventors: Joseph C. W. Spijkers, Eberhard Ruf, Diederich Schilo

Patent number: 5658673Abstract: An article which is sensitive to non-ionizing electromagnetic radiation in the radiofrequency radiation range, consisting essentially of a substrate, a layer of a binder material and a layer of activated diazoluminomelanin. This article is prepared by coating at least one surface of a substrate with a binder, immersing the binder-coated substrate into a solution comprising luminol, 3AT and a soluble nitrite for a period of about 2 to 12 days to provide a layer of diazoluminomelanin (DALM) on the binder layer, removing the DALM-coated film from the solution and rinsing the same, activating the DALM with sodium bicarbonate and hydrogen peroxide for a period of about 2 to 12 days.Type: GrantFiled: July 20, 1995Date of Patent: August 19, 1997Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Eric A. Holwitt, Johnathan L. Kiel, David N. Erwin

Patent number: 5648412Abstract: A rigid thermoplastic polyurethane with improved melt strength can be prepared by deactivating the catalyst for the polymer subsequent to the onset of urethane bond formation. Catalyst deactivation is accomplished either with a latent deactivator for the catalyst, or an active deactivator. The further addition of a crosslinker to the reaction mixture can provide an even greater improvement of melt strength.Type: GrantFiled: January 30, 1995Date of Patent: July 15, 1997Assignee: The Dow Chemical CompanyInventors: Gary S.
