Kinetics of interaction of m-chlorophenylisocyanate with hydroxyl end groups of oligobutadienes

A study was made of kinetics of interaction of m-chlorophenylisocyanate with oligobutadienols and oligobutadienediols of different molecular weights in the interval of 323–342°K. It was shown that the second order reaction rate constants decreases with a reduction in the concentration of OH groups....

Description
Summary:A study was made of kinetics of interaction of m-chlorophenylisocyanate with oligobutadienols and oligobutadienediols of different molecular weights in the interval of 323–342°K. It was shown that the second order reaction rate constants decreases with a reduction in the concentration of OH groups. Using kinetic and spectroscopic data a study was made of the effect on the rate of interaction of OH groups with each other and with π-electrons of CC bonds of oligomer. Heat effects of urethane formation were determined.
