Procedure

41.4 parts, by weight, of an isocyanate mixture consisting of 40%, by weight, of a tolylene diisocyanate mixture (2,4- and 2,6-isomers in proportions of 65:35) and 60%, by weight, of a crude polyphenyl-polymethylene-polyisocyanate (viscosity about 200 cP at 25° C.). The polyphenyl-polymethylene-polyisocyanate had been obtained by aniline-formaldehyde condensation followed by phosgenation.
