摘要:
A method for making over-indexed thermoplastic polyurethane elastomer precursor having unreacted isocyanate moities is presented, the method comprising: combining reactants and reacting them to form an over-indexed thermoplastic polyurethane elastomer precursor; cooling; pelletizing; drying; and packaging it in moisture-resistant packaging. A method for making over-indexed thermoplastic polyurethane elastomer, and a method for making an article therefrom are also presented.
