Title:
PHOTO-CROSS-LINKABLE SHAPE-MEMORY POLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/186575
Kind Code:
A1
Abstract:
The present invention relates to a photo-cross-linkable shape-memory polymer and a preparation method therefor. The shape-memory polymer according to one embodiment of the present invention comprises a photo-cross-linkable functional group, and thus a shape-memory polymer having a melting point suitable for a physiological or medical application device can be provided. Particularly, a method for preparing the shape-memory polymer, according to one embodiment of the present invention, uses a catalyst for inducing the simultaneous ring-opening polymerization of two monomers (CL, GMA) during synthesis of the shape-memory polymer, thereby enabling the synthesis time of the shape-memory polymer to be reduced, and shape-memory polymers having various melting points can be readily prepared by controlling the introduction amounts of CL and GMA.
