    摘要: A process for the preparation of urethanes. Urethanes having the general formula R.sub.1 (NHCOOR.sub.2).sub.n are reacted with an alcohol at a temperature of 120.degree. to 400.degree. C. in amounts such that, for every mol of the urethane, at least one mol of the alcohol is present. R.sub.1 is a radical obtained by removing the isocyanate groups from an n-functional organic isocyanate, which isocyanate has a boiling point greater than 100.degree. C. at atmospheric pressure. R.sub.2 is a radical obtained by removing the hydroxyl group from a monohydric alcohol which has a boiling point greater than 140.degree. C. at atmospheric pressure.

    摘要: Bis-(4-isocyanatophenoxy)-alkanes corresponding to the formula ##STR1## in which R represents a divalent, saturated aliphatic hydrocarbon radical having from 2 to 6 carbon atoms with at least two carbon atoms between the two ether oxygen atoms, andR' represents hydrogen or a methyl group with R' being the same on both rings,are produced by phosgenating the corresponding diamine or an adduct of the corresponding diamine. These diisocyanates are particularly useful in the production of isocyanate addition products having outstanding physical and mechanical properties.
