Abstract

A process for the preparation of solutions of polyurethane prepolymers in the organic solvents usable to obtain varnishes, characterized in that, to dilute the prepolymers, mixtures are used that comprise organic solvents devoid of hydroxy groups and nitrogenous compounds of general formula: **(See formula)** where n represents zero or one, X represents an arylene radical, R1 and R2 represent hydrogen atoms, alkyl, cycloalkyl or aryl groups or, when n equals zero, they form a heterocycle together with the nitrogen atom to which they are linked.
