Anaerobic adhesives consisting of polyalkoxy diacrylate ester of bisphenol a monomer and dimethylaminoethyl methacrylate monomer using hydroperoxide as catalyst

Anaerobically curable compositions comprising a diacrylate ester monomer and hydroperoxide as a latent initiator of polymerization in an amount sufficient to initiate polymerization of said monomer, the monomer being of the general formula:

• ##SPC5##
• where:
• the aromatic groups are benzene rings or other aromatic groups substituted or not;
• R.sub.1 and R.sub.2 represent hydrogen, alkyl, aryl or hydroxyalkyl groups, or halogen;
• and
• R.sub.3 and R.sub.4 represent ##EQU4## where n is an integer from 1 to 20 and particularly 1 to 5, and R.sub.5, R.sub.6 and R.sub.7 represent hydrogen, alkyl or alkoxy groups, or halogen, said compositions further comprising 5-60% by weight of the composition of dimethylaminoethylmethacrylate.
