Procedure

After heating 2 moles of tolylene diisocyanate at 40°C., one mole of diethylene glycol was added dropwise thereto during a period of 3 hours. After completion of the dropping, the reaction was carried out for 2 hours at 60°C. to obtain a diethylene glycol-tolylene diisocyanate adduct of an isocyanate equivalent of 220.

Workup

  1. waitAfter completion of the dropping, the reaction was carried out for 2 hours at 60°C.
