Abstract

Reactive systems for polymerizing ethylenically unsaturated compounds comprising a first component, comprised of ethylenically unsaturated compounds capable of polymerization, and a second component of a hardener system comprised of organoboron compounds which are stabilized with suitable oligomers. An organic peroxide (perester, hydroperoxide, perether and/or peranhydride)is admixed with the compounds. These components are mixed to form a polymer. The reactive system reaches full strength in reduced time with the use of the organic peroxide and are suitable for joining hard body materials in human or animal tissue, in particular in the surgical and/or dental sector, in the production of body-absorbable or body-resistant adhesives, cements, and/or filling compounds and for forming synthetic material moldings.
