Title:
INDUCED LIGHT-EMITTING POLYURETHANE AND PREPARATION METHOD THEREFOF
Document Type and Number:
WIPO Patent Application WO/2019/095116
Kind Code:
A1
Abstract:
The invention relates to the technical field of polyurethane polymeric materials, and particularly to induced light-emitting polyurethane and a preparation method of the induced light-emitting polyurethane. The polyurethane takes a hydroxy-terminated, carboxyl-terminated or amino-terminated polymer, polyisocyanate and a thiazole pyridine bicyclic chain extender as structural units. The preparation method enables the hydroxy-terminated, carboxyl-terminated or amino-terminated polymer, the polyisocyanate and the chain extender shown in formula (II) to react to prepare the induced light-emitting polyurethane. The induced light-emitting polyurethane provided by the invention comprises a thiazole pyridine bicyclic repetitive unit, is capable of realizing induced light-emitting, meanwhile, the thiazole pyridine bicyclic repetitive unit has good biocompatibility and can be metabolized by a body.
