Abstract

Polyurethanes are produced by reacting together an alkyl resin modified with an epoxy resin, and an isocyanate with at least two reactive NCO groups. Epoxy resins are made from epichlorhydrin and a dihydric phenol, e.g. diphenylolpropane or resorcinol. They may themselves be modified by reaction with other resins, e.g. phenol-, resorcinol-, urea- or melamine - formaldehyde resins. Suitable alkyd resins may for example be prepared as described in Specifications 719,539 or 736,953 or may be based on adipic or pimelic acids, with or without phthalic or maleic anhydride, and ethylene or diethylene glycol, trimethylol propane, glycerol or pentaerythritol. The alkyd is modified by the epoxy resin by heating, e.g. at 50-300 DEG C. The isocyanate, preferably m-toluylene diisocyanate, is added preferably in stoichiometrical proportion at room temperature. It may be dissolved in toluene. In examples: (1) an alkyd from succinic acid, phthalic anhydride, sebacic acid and glycerol is reacted with an epoxy resin and then converted to a stiff foam by mixing with m-toluylene diisocyanate and zinc oxide; (2) an alkyd from sebacic acid and glycerol modified with an epoxy resin is foamed with m-toluylene diisocyanate and zinc oxide; (3) an alkyd from phthalic, succinic, and sebacic acids and glycerol is modified with an epoxy resin and mixed with m-toluylene diisocyanate to form an adhesive. A solution of the mixture in an ethyl acetate-butyl acetate mixture may be employed as a lacquer. The nature of the final product can be controlled to some extent by adjustment of the acid number of the modified alkyd resin. The foamed products which may be produced in situ may be used as core layers of sandwich structures.
