摘要：
The influence of temperature on the magnitude of the synergetic effect of the catalytic system di(tributyltin)carbodiimide + triethylene diamine in reactions of 2,4-tolylene diisocyanate with macrodiols has been studied. For calculations of the reaction rate constants a differential-integral method based on the consequent-parallel reaction scheme was applied. A proportional increase of the maximal synergetic effect with increase of temperature has been established. A qualitative interpretation of the observation is presented.
