Abstract
Curable acrylate ester compositions having as an accelerator for the polymerization a hydrazine derivative of the formula R.sup.1 --HN--NH--CO--R.sup.2. Typical of the monomers are the polyalkyleneglycol dimethacrylates and the so-called urethane acrylates. Polymerization is preferably initiated by a peroxy compound such as cumene hydroperoxide, such a composition having anaerobic curing characteristics.
