Patent number: 4424299Abstract: The invention relates to a process for manufacturing unsaturated polyester resins with suppressed volatilization of monomer, useful in the manufacture of laminates, moulding compounds, varnish coatings and castings. It is known a process for manufacturing unsaturated polyester resins by dissolving unsaturated polyesters in monomers with the addition of paraffin, waxes, ceresin wax, emulsifiers forming emulsions of the "water-in-oil" or "oil-in-water" type. These additives suppress the volatilization of monomers, but they exhibit a limited solubility in the resin and a majority of them separate on the surface during curing of the polyester resin and, thus, reduce the adhesion capacity of the subsequent layers of resin or laminates to the previously cured substrate.It has been found that unsaturated polyester resins with suppressed volatilization of monomer can be prepared by dissolving the unsaturated polyester in the monomer and by introducing 0.005-5.Type: GrantFiled: April 5, 1983Date of Patent: January 3, 1984Assignee: Instytut Chemii PrzemyslowejInventors: Piotr A.

Patent number: 4405763Abstract: A thermosetting binder composition for coating, comprising:(I) (1) A non-acidic resinous saturated compound having a molecular weight of at least 900, and an alcoholic hydroxyl content of at least 0.2 eq./100 g;(2) A non-acidic polyester of a polycarboxylic acid cross-linking agent having more than one .beta.-hydroxyl ester group per molecule, and at least one of components (1) and (2) having an alcoholic hydroxyl functionality of more than 2, and(II) A transesterification-promoting metal salt or complex curing catalyst which is soluble in liquid hydrocarbons.For aqueous compositions, component (I) (1) is preferably a neutralized epoxy resin/amine adduct and component (II) should be insoluble in water; they can be used for cathodic electrodeposition.Type: GrantFiled: February 16, 1982Date of Patent: September 20, 1983Assignee: Shell Oil CompanyInventors: Petrus G. Kooymans, Johannes J. M. H. Wintraecken, Werner T. Raudenbusch, Josepha M. E. Seelen-Kruijssen, Gerardus C. M. Schreurs

Patent number: 4398009Abstract: The invention relates to oligomeric and/or polymeric precursor stages of polyoxazoles, as well as to a method for the preparation of these precursor stages. New radiation-reactive polymer precursor stages are provided comprised of addition products of olefinically unsaturated monoepoxides on hydroxyl group-containing polycondensation products of aromatic and/or heterocyclic dihydroxy diamino compounds with dicarboxylic-acid chlorides or esters. The radiation-reactive precursor stages according to the invention are suitable, for example, for the preparation of highly heat-resistant relief structures and as coatings for the optical fibers of light waveguides.Type: GrantFiled: August 19, 1980Date of Patent: August 9, 1983Assignee: Siemens AktiengesellschaftInventors: Hellmut Ahne, Eberhard Kuhn, Roland Rubner

Patent number: RE32029Abstract: A copolyester resin having modified termini is disclosed, as well as the method for making and using that compound in subsequent reactions with epoxide curing compounds. The polymerization of the copolyester resin may include a compounding preparation stage for modifying the termini of the copolyester resin by reacting those end groups with an aromatic acid to alter the activation energy necessary to cure the modified copolyester resin with the epoxide compound upon mixing and heating of that mixture in a powder coating upon a substrate. The modified copolyester resin improves impact strength and leveling properties between 300.degree. and 450.degree. F., which is desirable for protection of the underlying substrate.Type: GrantFiled: December 20, 1984Date of Patent: November 12, 1985Assignee: The Goodyear Tire & Rubber CompanyInventors: Patrick J. Pesata, Jr., Harlan W. Frerking, Jr., Nelson C. Bletso
