In a surgical composition comprising a liquid monomeric and powdered polymeric acrylate or methacrylate, a catalyst and an accelerator, the composition upon mixing of the liquid and powdered constituents passing through a plastic state to a solid state, the improvement which comprises including in the composition about 1 to 15% by weight of dimethyl sulfoxide. The product exhibits reduced cytotoxicity.

Surgical material

Surgical material based on liquid monomeric and pulverulent polymeric acrylates and/or methacrylates, catalysts, accelerators and, if appropriate, customary additives, which passes via a plastic state into the solid state by mixing of the liquid and pulverulent components, and which contains 1-15% by weight, based on the total weight, of one or more non-toxic, liquid aliphatic, saturated mono-, di- or tri-carboxylic acids with 1-6 carbon atoms and, if appropriate, 1 or 2 hydroxyl groups, completely or partially esterified with mono-, di- or tri-hydric alcohols with 1-4 carbon atoms, or liquid ethylene glycols or 1,2- or 1,3-propylene glycols with in each case 2 to about 30 glycol units, these liquids having a boiling point above 100.degree. C., preferably above 150.degree. C.

A composition which is particularly useful in semi-rigid medical supporting bandages comprising

Composition for the production of bandages, bandages produced therewith

A powder mixture for surgical use, containing a methyl methacrylate homopolymer and/or copolymer powder, an X-ray contrast medium powder and a polymerization initiator, wherein the polymerization initiator is present as a combination product with the polymer powder or the X-ray contrast medium. This powder mixture is suitable for the preparation of surgical compositions which harden and are based on polymethyl methacrylate or its copolymers.
