Patent number: 6458875Abstract: The present invention is embodied in a polyurethane composition suitable for coating, casting or laminating, which incorporates a prescribed additive selected to increase the composition's electrical conductivity without adversely affecting the composition's transparency and percent haze and without adversely affecting its adhesion to an underlying substrate or its environmental durability, especially with regard to humidity resistance. The prescribed additive is an ionizable metal salt of a perfluoroalkylsulfonimide, in a weight percent of 0.5 to 5.0, with the metal being an alkali metal and the preferred perfluoroalkylsulfonimide being trifluoromethanesulfonimide. The most preferred salt is lithium trifluoromethanesulfonimide. The preferred polyurethanes include both aliphatic polyetherurethanes and aliphatic polyesterurethanes.Type: GrantFiled: June 1, 2000Date of Patent: October 1, 2002Assignee: Pilkington Aerospace Inc.Inventors: Stephen L. Sandlin, Lin Hin Hoo, Marlowe V. Moncur

Patent number: 5378535Abstract: Primer systems foe silicone elastomers bonded to glass or plastic substrates, particularly those elastomers used as interlayer materials in a transparent lamination of such substrates, are described. The primer system consists of a thin layer of a silica-based adhesion promoter which is applied directly to at least one surface of the substrate. An organosilane primer containing (i) silanol or functional groups that can hydrolyzed to silanol, and (ii) polymerizable alkene or silicon hydride functional groups, or preferably both, is applied over the silica-based adhesion promoter layer. Alternatively, the silicone elastomer may also contain silanol groups or functional groups that can be hydrolyzed to silanol, and polymerizable alkene or silicon hydride functional groups, thereby making a separate primer layer unnecessary. Both components must be present for the primer system to provide a more durable adhesive bond.Type: GrantFiled: July 29, 1992Date of Patent: January 3, 1995Assignee: Pilkington Aerospace, Inc.Inventors: Marlowe V. Moncur, Janet A. Andrechak, Clifford D. Jeungst

Patent number: 4622377Abstract: A plastic transparency, and method for making it, that is the polymerization product of at least 97.5 mole percent of a monofunctional, vinyl monomer, of which at least 70 percent and preferably 100 percent is methyl methacrylate, and up to 2.5 mole percent neopentylene glycol dimethacrylate. The transparency exhibits significantly reduced optical hazing in an acidic environment, making it particularly suitable for use as an aircraft transparency.Type: GrantFiled: January 21, 1986Date of Patent: November 11, 1986Assignee: Swedlow, Inc.Inventor: Marlowe V.

Patent number: 4234674Abstract: The present invention relates to amino-functional photopolymer compositions and to photo-oxidation imaging processes utilizing such compositions. The amino-functional photopolymer compositions comprise amino-functional polymers. For example, other polymers or resins without amino-functionality may be incorporated to aid in adapting the compositions for use in particular applications as are discussed herein.Type: GrantFiled: August 8, 1979Date of Patent: November 18, 1980Assignee: Monsanto CompanyInventors: James C. Woodbrey, Marlowe V. Moncur

Patent number: 4188223Abstract: The present invention relates to amino-functional photopolymer compositions and to photo-oxidation imaging processes utilizing such compositions. The amino-functional photopolymer compositions comprise amino-functional polymers and photosensitizing agents which, when exposed to electromagnetic radiation in the presence of ordinary molecular oxygen, are cured, thereby forming a less soluble polymer. Where the irradiation has been done selectively or in an imagewise fashion, the compositions allow for the development of an image by virtue of the solubility or redispersibility differential between the exposed and unexposed portions of the compositions. The amino-functional photopolymer may be any of a large variety of types, but generally will comprise a polymer with two or more amino-functional groups. The polymer may be a soluble polymer or a small-particle-size microgel cross-linked polymer. The photopolymer may also comprise mixtures of soluble polymer and small-particle-size microgel cross-linked polymer.Type: GrantFiled: December 30, 1977Date of Patent: February 12, 1980Assignee: Monsanto CompanyInventors: James C.
