Curable epoxy compositions comprise: (1) an epoxy compound having on average more than one epoxy group per molecule, and (2) a curing amount of at least one metal salt catalyst of formula M (X Fn)p where M is lithium or a Group II metal, X is boron, arsenic, antimony or phosphorus, n is 4 when X is boron and is 6 when X is arsenic, antimony or phosphorus, and p is 1 when M is lithium and 2 when M is a Group II metal, and, optionally, (3) a miscible amount of at least one ethylenically unsaturated monomer. The metal salt catalyst may be incorporated into the curable composition in a pre-prepared catalyst composition. Formed articles are prepared by forming and curing the curable compositions. |
