Estimating the term…
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.
Reactive system comprising a first component comprised of ethylenically unsaturated reactive compounds capable of polymerization, and a second component of a hardener system comprised of organoboron compounds which is stabilized with oligomers, wherein the first component and second component are mixed for use of the reactive system and wherein an organic peroxide having a half-life at 80° C. in the range of from hours to days, selected from t-butyl peroxy benzoate or di-tert-butyl peroxide, is dissolved in the ethylenically unsaturated reactive compounds in an amount between 0.005 to 10% by weight, based on the weight of ethylenically unsaturated reactive compounds.
