Abstract: Carbodiimides which are solid at 25 degrees C, containing carbodiimide structures which are attached to non-aromatic carbon atoms, together with urethane and/or urea structures. Independent claims are also included for: (a) a process for the production of these solid carbodiimides from di-isocyanates in which the isocyanate (NCO) groups are not attached to aromatic carbon, by reaction in presence of catalysts to form the carbodiimide with cleavage of carbon dioxide, followed by reaction with compounds containing at least two NCO-reactive groups; (b) another process in which the above stages are reversed and the ratio of NCO groups to NCO-reactive groups used in the first stage is at least 2:1; (c) solid carbodiimides obtained by these processes; (d) mixtures containing compounds with ester units together with these carbodiimides; and (e) mixtures containing these carbodiimides and at least one of the following: polyurethanes with ester units and/or polycondensation products such as polyesters, e.g. polyethylene- or polybutylene- terephthalate, polyether-esters, polyester-esters, polyester-amides, polycaprolactones, unsaturated polyester resins and polyamides.

Abstract: In a process for preparing solutions containing at least one isocyanate, the above-defined solution is subjected to a treatment with hydrogen after the phosgenation and before the complete removal of the solvent and of residual phosgene. A process for preparing isocyanates or isocyanate mixtures is provided, and the isocyanates thus prepared can be used for preparing polyurethanes, in particular polyurethane foams.
