Procedure

117 g (1 mol) of 2-(1,3-oxazolidin-3-yl)-ethanol are reacted with 84 g (0.5 mol) of hexamethylene diisocyanate in 20 g of xylene by the method described in Example 1. This reaction is catalyzed by the addition of 0.05 g of Sn(II) octoate and is carried out first at 30° C and later at 50° C. The product obtained, which is about 90% pure, is solid at room temperature, but a pourable liquid at 50° C.
