Curable compositions, especially suitable for use as adhesives, contain (A) an anaerobically polymerizable mixture which is stable in oxygen but polymerizes when oxygen is excluded, comprising (i) a free radical polymerizable compound, such as an acrylate or methacrylate ester, (ii) an organic free radical initiator, such as a peroxide or hydroperoxide, and (iii) an organic accelerator of free radical polymerization (B) an epoxide resin, and (C) a curing agent for epoxide resins that is a basic curing agent, a polymercaptan, or a polyhydric phenol. These compositions cure rapidly by an araerobic curing mechanism and then develop high strength by cure of the epoxide resin.

A method of effecting adhesion between two impervious surfaces that comprises applying to at least one of the surfaces a curable composition which is polymerizable by excluding oxygen therefrom and which is further curable by heating, comprising (A) an anaerobically polymerizable mixture which is stable in oxygen, but is polymerizable by excluding oxygen therefrom, comprising (i) an acrylic ester of formula II, IV or VI [Figure] II where R1 denotes -H, -Cl, -CH3 or -C2H5, R denotes H, -CH3, -C2H5, -CH2OH, or -CH2O-CO-C(R1)〓CH2 R2 denotes H, OH, or -OCO-C(R1)〓CH2 a is an integer of from 1 to 8, b is an integer of from 1 to 20, and c is zero or 1, [Figure] IV where c is zero or 1, e is 2, 3 or 4, R4 denotes -H or -CH3, and R5 denotes an organic radical of valency e, linked through a carbon atom thereof other than a carbon atom of a carbonyl group. R8-C(R9)13 (CH2OCO-C(R1)〓CH2)2 VI where R1 denotes -H, -Cl, -CH3 or -C2H5, R8 denotes CH3-, C2H5-, -CH2OH or CH2〓C(R1)COOCH2-, and R9 denotes -CH2OH or -CH2OOC-C(R1)〓CH2. (ii) an organic free radical initiator, and (iii) an accelerator of free radical polymerization which is benzoic sulfimide, diethyl phosphoro hydrazidate, or a mixture of benzoic sulfimide and N,N-dimethyl-p-toluidine, (B) an epoxide resin, and (C) a basic curing agent for epoxide resins which is dicyandiamide or an imidazole, wherein the composition is subject to anaerobic polymerization by excluding oxygen therefrom and curing either at room temperature or at elevated temperature, applying a second surface to the composition, and holding the surfaces together to prevent the ingress of oxygen until the composition solidifies.
