ABSTRACT:
In-situ plasticized thermoplastic polyurethane (TPU) compositions are made by a process which involves reacting a polyol, glycol chain extender and a polyisocyanate where the reaction is conducted in the presence of a plasticizer. The reactants together with the plasticizer are added to a reaction extruder and reacted to form the in-situ plasticized TPU.
