| titleOfInvention | Main chain biodegradable liquid crystal polymer and preparation method thereof |
| abstract | The invention belongs to the technical field of biodegradable medical polymer materials, and particularly relates to a main chain type biodegradable liquid crystal polymer and a preparation method thereof. Using natural products such as cholesterol, diosgenin, menthol, and isosorbide as the liquid crystal nucleus, and hydroxy-terminated alkanoic acid or terminal amino acid as the flexible spacer to prepare the liquid crystal intermediate, and using it as the initiator to trigger trimethylene carbonate, Monomers such as caprolactone, lactide, glycolide, p-dioxanone, propiolactone, butyrolactone, caprolactone, caprolactam, morpholine-2,5-dione, dianhydride and the like The ring-opening polymerization reaction of one or two or more of the derivatives, and then the main chain type biodegradable liquid crystal polymer is obtained. The main chain biodegradable liquid crystal polymer involved in the present invention has good liquid crystal properties, is easy to orient to form an ordered structure, not only responds to the outside world such as temperature, pH, stress, electric field and magnetic field, but also has good biocompatibility and degradation properties. |
