Patent number: 5494981Abstract: A polymerizable composition of matter comprises a cycloaliphatic epoxy resin, a cyanate ester resin, optionally a polyol, and, as initiator, a Bronsted acid. When cured, the compositions provide interpenetrating polymer networks (IPNs). The IPNs are useful as high temperature stable vibration damping materials, adhesives, binders for abrasives, and protective coatings.Type: GrantFiled: March 3, 1995Date of Patent: February 27, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Ilya Gorodisher, Michael C.

Patent number: 5488085Abstract: Polymer polyols prepared by a semi-batch process using a small amount of a seed polymer polyol are disclosed. The final polymer polyol has a broader particle size distribution as compared to an identically prepared polymer polyol prepared in the absence of the seed polymer polyol. The polymer polyols are suitable for use in producing polyurethanes, particularly polyurethane foams.Type: GrantFiled: August 18, 1994Date of Patent: January 30, 1996Assignee: ARCO Chemical Technology, L.P.Inventors: John E. Hayes, Donald W. Simroth, Xinhua Zhou

Patent number: 5478870Abstract: An aqueous resin dispersion which comprises as the chief component acrylic-modified epoxy-polyamine resin composed of a bisphenolic epoxy resin containing at least two epoxy groups per molecule; and, as bound to at least a part of said epoxy groups, an acrylic resin having on the average at least one functional group which is capable of reacting with said epoxy group, per molecule, the molecular weight distribution of said acrylic resin as expressed by its weight average molecular weight (Mw)/number average molecular weight (Mn) being within a range of 1 to 1.2, and an active hydrogen-containing amino compound. Said aqueous resin dispersion may further optionally contain non-ionic, film-forming resin. Such dispersions are useful for cationic electrodeposition paint which can form a coating excelling in weatherability and corrosion resistance.Type: GrantFiled: August 25, 1994Date of Patent: December 26, 1995Assignee: Kansai Paint Co., Ltd.Inventors: Masanobu Kudoh, Hidehiko Haneishi

Patent number: 5426157Abstract: This invention relates to improved polyepoxide resins having enhanced physical and elastic properties. The polyepoxide resins comprise a polyepoxide resin based on a polyglycidyl ether of a phenolic-type compound and an acrylate-terminated urethane prepolymer. The improvement in the polyepoxide resin formulation comprises incorporating a polymethylated amine curative having two secondary amine hydrogens represented by the formula: ##STR1## wherein R is alkylene or polyalkylene polyamine having from 2 to 20 carbon atoms. The presence of the aliphatic amine reactive component along with the acrylate-terminated urethane prepolymer results in an epoxy resin having enhanced properties.Type: GrantFiled: March 16, 1994Date of Patent: June 20, 1995Assignee: Air Products and Chemicals, Inc.Inventors: William E. Starner, John A. Marsella, Richard S. Myers
