Abstract: One or both surfaces of a polyimide sheet are uniformly and completely textured and can be coated with a layer of electroless nickel or cobalt and a subsequent layer of electrolytically applied copper yielding an adhesiveless laminate useful in the production of electronic circuitry. The copper and nickel or cobalt layers can be strongly bonded to the textured polyimide sheet to the extent that the laminate exceeds bond strength requirements as measured by current standard peel strength tests of the Institute for Interconnecting and Packaging Electronic Circuits (IPC) for both initial and post solder float adhesion.
Abstract: A bituminous building sheeting which is compatible with hot mopping bitumen and bituminous cold adhesives and whose covering mass is modified with APP and IPP. The mass, homogenized under high shear forces is cooled off after the application of 180.degree. to 200.degree. C. at a cooling speed of not more than 120 K/min. Polymer spherulites form on the surface thereby which improve the adhesiveness and prevent oily components from exuding out of the bitumen.
