| titleOfInvention | Biodegradable thermoplastic polyester elastic material and preparation method thereof |
| abstract | The invention relates to a biodegradable thermoplastic polyester elastic material and a preparation method thereof. The method comprises the following steps: mixing sebacic acid and polyethylene glycol, stirring, carrying out esterification reaction under a vacuum condition, adding a catalyst, carrying out pre-condensation reaction under the vacuum condition, continuously reacting the obtained prepolymer, and purifying. The reaction monomer adopted by the method is simple, non-toxic and non-irritant, has good biological safety, is widely applied in biomedicine, and the obtained material has good biocompatibility and biodegradability. |
