Patent number: 6492462Abstract: The rheological properties of a crosslinkable resin system are modified by the presence of a side chain crystalline (SCC) polymer (or a similar crystalline polymer which melts over a narrow temperature range). The polymer dissolves in the curable system at temperatures above the melting point of the crystalline polymer (Tp), but when the system is then cooled to a temperature below Tp, at least partially forms a separate phase in the curable system. Below Tp, this separate phase substantially increases the viscosity of the curable system (i.e. makes it thicker than the same system without the crystalline polymer). This is particularly valuable for sheet molding composites (SMCs) in which the increase in viscosity makes the composites less tacky, and for dry film resists (DFRs). Above Tp, the curable system containing the dissolved crystalline polymer has a viscosity which is substantially less than its viscosity below Tp.Type: GrantFiled: December 19, 2000Date of Patent: December 10, 2002Assignee: Landec CorporationInventors: Steven P.

Patent number: 4981921Abstract: Water-dilutable binders for water-dilutable lacquers, coating compositions or sealing compounds consist essentially of a mixture of 5 to 40 parts by weight of a crosslinker resin and 60 to 95 parts by weight of a copolymer containing carboxyl groups or acid anhydride groups or both and further containing hydroxyl groups, and wherein the carboxyl or acid anhydride groups have been at least partially converted into carboxylate groups to the degree necessary to provide solubility or dispersibility of the binder in water and said copolymer is obtained by copolymerizing an alpha, beta-unsaturated carboxylic acid, a hydroxyalkyl acrylate or methacrylate, an olefinic monomer, a hydroxy-free acrylate or methacrylate and, optionally other mono-or polyunsaturated monomer, and wherein at least 30% of the hydroxyl groups of the copolymer are modified by esterification with a lactone.Type: GrantFiled: December 30, 1988Date of Patent: January 1, 1991Assignee: Bayer AktiengesellschaftInventors: Harald Blum, Peter Hohlein, Wolfhart Wieczorrek

Patent number: 4692272Abstract: A novel adhesive exhibiting low outgassing upon exposure to high temperatures is disclosed. The instant adhesive comprises: (a) a soluble polyimide resin, (b) a solvent for said polyimide resin, (c) an epoxy resin, (d) a cross-linking agent reactive with the polyimide solvent of (b), and (e) a catalyst which accelerates the reaction between (b) and (d). Optionally, the adhesive may also contain a conductive material. A process for making the adhesive is also disclosed.Type: GrantFiled: September 12, 1985Date of Patent: September 8, 1987Assignee: Stauffer Chemical CompanyInventors: Jagadish C. Goswami, Joseph A.
