Curable acrylate ester compositions having as an accelerator for the polymerization a hydrazine derivative of the formula R1-HN-NH-CO-R2. Typical of the monomers are the polyalkylene-glycol 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. |
