Abstract: The present invention relates to a process for preparing a cyclic isocyanate (B) from a composition (Z) which comprises at least one component (A) which has at least one cycloalkane ring having at least 4 ring carbons, where the cycloalkane ring has two NH2 groups in β or γ positions relative to one another as substituents and in more than 50 mol % of the total amount of component (A) the two NH2 groups in β or in γ positions relative to one another assume a trans configuration relative to one another. This composition (Z) is, in the process of the invention, reacted with phosgene to give a composition (ZP) which comprises at least one cyclic isocyanate (B) having isocyanate groups.In addition, the invention relates to the use of the isocyanate mixture (M) as monomer in processes for preparing polymers, in particular for preparing polyurethanes and polyureas.
