Curable compositions contain: (a) at least one nitrile oxide monomer which contains on average more than one stable nitrile oxide group per molecule; and (b) at least one polyunsaturated monomer which: (1) has a weight average molecular weight of no more than 5000; and (2) contains on average more than one insaturated moiety which contains a sterically-unhindered carbon-carbon or carbon-nitrogen double bond or triple bond. The monomers are selected such that either the nitrile oxide monomers or the polyunsaturated monomers or both contain on average more than two reactive groups per molecule, and such that the equivalent ratio of nitrile oxide to unsaturated moieties is more than 0.5:1 and less than 2:1. The compositions can be used in coatings, composites, laminates and injection moldings. |
