Zusammenfassung:	PURPOSE:To provide an anaerobic adhesive compsn. having excellent workability, heat resistance, etc., and suitable for use in fixing treaded parts, etc., containing a (meth) acryloyl group-contg. (meth) acrylic oligomer, a maleimide compd. and a free radical-generating polymn. initiator. CONSTITUTION:A (meth) acrylic oligomer (A) contg. at least one (meth) acryloyl group per molecule (e.g. ethylene glycol diacrylate oligomer or trimethylol- propane triacrylate oligomer), a maleimide compd. (B) of the formula (wherein R1, R2 are each H, halogen, a 1-4 C alkyl; R3 is a 3-8 C alkyl) such as N-butylmaleimide or N-isopropylmaleimide and a free radical-generating polymn. initiator (C) (e.g. t-butyl hydroperoxide or cumene hydroperoxide) are mixed together to obtain the desired anaerobic adhesive compsn.
