Ashland Oil, Inc. - Russell KY
International Classification:
C08L 6706
US Classification:
525 28
Abstract:
Thermoset polymers are prepared by reacting an ethylenically unsaturated resin monomer and a bicyclic amide acetal with a polyisocyanate in the absence or presence of a vinyl monomer. Reaction rates are suitable for effecting RIM processing. The resultant polymers exhibit improved impact resistance. Further variation in physical properties can be achieved through the use of a diol chain extender for the polyisocyanate.

International Classification:
C01C 300 C01C 314
US Classification:
423365
Abstract:
Isocyanic acid is formed directly from nitric oxide, carbon monoxide and hydrogen by contacting a supported iridium or rhodium metal catalyst at an elevated temperature with a feed stream of said reactants.
Polyurethane Pressure Sensitive Adhesives For Bonding Layered Structures
A process for the production of a pressure sensitive adhesive comprising the interaction of a high molecular weight polyol, a polyisocyanate and a small amount of a bicyclic amide acetal wherein the process results in significant improvement in physical properties, e. g. , a high degree of adhesive and cohesive strength, is described.

Assignee:
Ashland Oil, Inc. - Ashland KY
International Classification:
B32B 2538 C09J 504
US Classification:
428414
Abstract:
A process for preparing novel composite structures by priming the surfaces of two or more substrates (such as SMC panels, etc. ) with an effective amount of an epoxy resin prior to adhering said surfaces together with an adhesive (such as a polyurethane adhesive) wherein said structures have improved high temperature (about 400. degree. F. ) tolerance is described.
