Title:
THERMOPLASTIC POLYURETHANE ELASTOMER WITH HYDROLYTIC STABILITY AND PREPARING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2009/079826
Kind Code:
A1
Abstract:
A hydrolysis-resistant thermoplastic polyurethane elastomer comprises carbodiimide-modified organic diisocyanate used as hydrolysis-resistant aids and thermoplastic polyurethane elastomer matrix. A method for preparing thermoplastic polyurethane elastomer comprises mixing hydrolysis-resistant aids and raw materials for thermoplastic polyurethane elastomer matrix, and then reacting the mixture by means of pre-polymer process, conveyor band process or twin-screw reactive extruder process.
