Abstract
Significant improvements in the utility of oxazolidone and polyoxazolidone compounds and in their manufacture can be achieved using a novel catalyst in the reaction between a hindered isocyanate and an epoxy, forming oxazolidone ring structures. The novel catalyst of the invention promotes the efficient and rapid formation of oxazolidone and polyoxazolidone compounds. The use of hindered isocyanate in the reaction prevents formation of side reaction products such as isocyanate trimer, allophanate and biuret.
