Beschreibung
Zusammenfassung:	The present invention provides a method which uses organic diamine modified montmorillonite as diamine chain-extending agent of polyurethane polymer to make organic diamine montmorillonite/polyurethane nano composite polymer so as to raise heat resistance of polyurethane elastic fibre and raise its mechanical property. The described montmorillonite is sodium base montmorillonite, and the polyurethane polymer is formed from polyether polybasic alcohol, isocyanate, linear fatty amine and organic diamine montmorillonite.
