Abstract

The polyurethanes which have emerged as important industrial and biomedical engineering materials were synthesised by reaction of isocyanates with alcohols. Their reaction kinetics in the apolar solvents have been widely studied[1-3]. In the polar solvents which are really used in the practice synthesis, their reaction velocities are much higher than in the apolar solvents. Since the FT-IR spectroscopy has rapid and sensitive advantages, It has been applied to study the reaction of isocyanates in the formation of plastic foams [4], here we tried to study the reaction kinetics of 4,4'-diisocyanatediphenylmethane ( MDI ) with 1,4-butanediol (1,4-BD) in N,N-dimethylformamide(DMF) or dimethyl sulfoxide (DMS0) solvents utilizing this technique.
