Abstract
Process for obtaining physiologically compatible urethaneisocyanates by reaction of low molecular weight compounds, containing one or more hydroxyl groups that react with the nco groups, or of their mixtures with tolylene diisocyanate, characterized in that once the reaction has been carried out the parts of the monomeric diisocyanate those remaining are trimerized by addition of known polymerization catalysts for the isocyanate groups at temperatures below 60ยบ c.
