Abstract

Critical chromatography is used to study the kinetics of reactions between polypropylene glycols and phenyl butyl isocyanate that simulate the production of polyester urethanes. The use of a two-detector version of chromatography makes it possible to monitor the concentration of the original, intermediate, and final oligomers and reveal the effect of one end group on the reactivity of the other separated by a long chain. The processing of the kinetic data makes it possible to determine the reaction-rate constants for macromolecules of different functionalities and to quantitatively describe the process behavior.
