The first high-temperature endotherm (T1) of polyurethane hard segment based on 4,4‘-diphenylmethane diisocyanate (MDI) and 1,4-butanediol (BD) was studied by differential scanning calorimetry (DSC). The materials contain 69% (w/w) of MDI and BD as

The long-term confusing glass transition temperature, Tg, and specific heat capacity, ΔCp, of the 4,4‘-diisocyanatodiphenylmethane (MDI) and 1,4-butanediol (BD) hard segment in segment polyurethanes have been clearly evidenced by using a new serie
