Abstract
Described is the use of physiologically compatible tocopherols and especially of vitamin E as an inhibitor against premature polymerization initiation in reactive systems capable of undergoing a free radical-initiated polymerization, which systems before and/or after the polymerization thereof are placed in tissue contact with the living human or animal body and, more specifically, are implanted into the living organism thereby. The reactive systems and the polymers formed therefrom may be degradation resistant. However, a special embodiment relates to compositions or molded bodies which are decomposed by the living organism, and especially so under time-controlled conditions. The invention further relates to surgical binder systems which are suitable for adhesion bonding endogenous body tissue and which have been based on an adhesive component capable of being activated by free radicals, said adhesive component being present in admixture with a free radical inhibitor and being characterized in that the inhibitor or at least the predominant portion of the inhibitor is vitamin E. It is preferred that the described compositions are free from physiologically unacceptable solvents or residual amounts of solvents left from the preparation process.
