Inhibitor concentrate, storage stable unsaturated thermosettable resins and cured products.

摘要

Thermosettable ethylenically unsaturated resins are rendered storage stable by the addition of a member selected from the group consisting of (1) at least one 1,4-naphthoquinone substituted on the 2 or 3 or both the 2 and 3 positions; (2) a complex formed by mixing (a) at least one quinonoid compound and (b) at least one imidazole compound; and (3) any combination of (1) and (2). The reactivity of these storage stable resins with curing agents is not significantly reduced by the presence of the stabilizer complex.
