Abstract: Curable resin compositions are prepared containing a radiation-sensitive reactive diluent and a saturated polyol. Curing is accomplished by mixing the reactive diluent and the polyol with a polyisocyanate, followed by exposure of the resultant composition to radiation to polymerize the reactive diluent and then, by thermal curing, to form the hydroxyisocyanate (urethane) linkage. The fully cured resin composition is described as interpenetrated or one in which there is no cross-linking between the reactive diluent and urethane linked co-polymer. The interpenetrated resin compositions form tough and hard coatings on various substrates.

Abstract: Disclosed herein are tricyclic and pentacyclic polyamines having a secondary or tertiary amine group on an amine functional substituent and at least one primary amine group on each of two amine functional substituents in the molecule. These compounds function excellently as non-visibly carbonating epoxy curing agents and in addition unlike most other amines exhibit a mild amine odor.

Abstract: Certain benzothiazine compounds, metal complexes thereof and solutions of said compounds in essentially water-immiscible, liquid hydrocarbon solvents are disclosed. These compounds have in their 4-keto form, the structure: ##STR1## the corresponding enol of which has the structure: ##STR2## wherein x, n, R.sup.1, R.sup.2 and R.sup.3 are as defined in the specification and claims hereof. Particular metal values are recovered from their aqueous solutions by using the benzothiazine compounds dissolved in essentially water-immiscible, liquid hydrocarbon solvents. The extraction process involves contacting the metal value containing aqueous solution with the solution of the benzothiazine in essentially water-immiscible, liquid hydrocarbon solvent and stripping the metal from the loaded organic phase.
