Tdi dimer
WebThe dimerization reaction is per se rather unsuitable for polymer syntheses from diisocyanates because of the almost perfect reversibility of reaction (15) at even moderate temperatures; for example thermal splitting of dimers of toluene 2,4-diisocyanate (TDI) and of diphenylmethane 4,4′-diisocyanate (MDI) occurs completely at 175 °C and ≥ ...
