A recycling model of excess toluene diisocyanate isomers in the preparation of polyurethane prepolymer

Reaction kinetics of dropwise addition of trimethylolpropane (TMP) to toluene diisocyanate (TDI‐80) at various temperatures and initial stoichiometry was studied. The progress of the polymerization reaction was monitored by measuring the concentration of isocyanate groups and TDI isomers by means of...
