Abstract

The present invention relates to an amphiphilic polymer copolymer composed of a prepolymer polymerized by reacting polyol (P) and diisocyanate (R) and a chain-extender comprising one or more hydrophilic or hydrophobic functional groups (Eor E) and a method for preparing the same. Such a polymer is a biocompatible polymer as a thermoplastic polyurethane polymer, and it can be used as various medical polymers, and it has an advantage that a process can be simplified as it is easier to prepare and configure than the conventional blended medical polyurethane.
