Process for preparing thermoplastic polyurethanes

Production of thermoplastic polyurethane elastomers (TPU) involves (A) mixing (a) linear hydroxyl (OH)-terminated polyol(s) (molecular weight (Mw) 500-5000) with (b) organic diisocyanate in isocyanate (NCO)-reactive/NCO group equivalent ratio of (1.1-5.0):1 in mixing aggregate with high shear energy...
