HDI monomer trimerization reaction with tetramethyl ammonium hydroxide (TMAH) as catalyst, was carried out by solution polymerization process. The free HDI monomer content of the sample were determined by gas chromatography. The data and spectrum were analyzed to study the reaction kinetics and obtain reaction kinetics curves. Two major stages in reaction process were both confirmed the first order reaction. The reaction kinetic equations γ_1 = 5.08 × 10~(-2)c [HDI], γ_2 = 1.07 × 10~(-2)c[HDI] respectively.
