実験手順
The batch is then diluted with 185.0 parts of toluene and a mixture of 180.0 parts of the semi-blocked toluylene diisocyanate referred to in Example 1 and 150.0 parts of a semi-blocked toluylene diisocyanate obtained from 2-ethylhexanol and an 80/20 toluylene diisocyanate isomer mixture is added in the course of 2 hours 15 minutes at 90° C. After completion of this addition, stirring is continued for 1 hour at 90° C., and the mixture is then heated to 120° C., kept at this temperature for 3.5 hours, and diluted after cooling with 81 parts of toluene. The solids content of the resulting polyether-polyol derivative containing blocked isocyanate groups, ie. of component A, is 71%.
