專利摘要(中)
A method for preparing a biodegradable polyester elastomer includes a step of carrying out an esterification reaction to produce a glycerol-sebacic acid prepolymer, a glycerol-maleic acid prepolymer, or a glycerol-adipic acid prepolymer. The esterification reaction is carried out between sebacic acid, maleic acid, or adipic acid and glycerol in a molar ratio of 1:1-2 with an effective amount of sulfated titania under a vacuum pressure of 300-600 mTorr. Therefore, the production time of the biodegradable polyester elastomer can be reduced significantly.
