Patent number: 4302511Abstract: A laminate structure having at least one layer of a polyamide containing from 0.001 to 1.0 parts, based on the weight of the polyamide, of a copper cation containing material. The polyamide layer is contiguous to at least one opposing layer. The opposing layer contains an effective amount of functional groups selected from the group consisting of acid groups, metal salts of the acid, acid anhydrides, carbonates and mixtures thereof.Type: GrantFiled: December 29, 1980Date of Patent: November 24, 1981Assignee: Allied CorporationInventors: Harold W. Tuller, Stephen R. Schulze, Charles D. Mason

Patent number: 4264650Abstract: Disclosed is a method for coating substrates with a stress-crack resistant coating of a fluoropolymer and a polyfunctional compound having two or more allyl groups such as triallylcyanurate or triallylisocyanurate wherein the fluoropolymer is a polymer comprised of ethylene, chlorotrifluoroethylene or tetrafluoroethylene and optionally a termonomer such as 3,3,3-trifluoro-2-trifluoromethyl propene. The ingredients are homogeneously blended and applied to the substrate which is maintained at an elevated temperature to allow flow-out of the coating mixture thereby forming a stress-crack resistant coating.Type: GrantFiled: February 1, 1979Date of Patent: April 28, 1981Assignee: Allied Chemical CorporationInventors: Stephen R. Schulze, Elmer C. Lupton, William A. Miller, Robert H. Hutzler
