| titleOfInvention | Method for preparing high-impact-toughness polylactic acid compound by reactive blending of vegetable oil derivatives |
| abstract | The invention discloses a method for preparing a polylactic acid compound with high impact toughness by reactive blending of vegetable oil derivatives. The method adopts carboxyl groups or hydroxyl groups and carboxyl groups at two ends of a toughening monomer a to carry out high-activity condensation reaction with isocyanate groups of a toughening monomer b; and if the toughening monomer a also contains unsaturated C ═ C double bonds, then carrying out free radical crosslinking reaction again, in the process of melt blending with PLA, generating in situ a bio-based elastomer toughening phase which has good compatibility with the PLA matrix and is uniformly dispersed, and finally preparing the required product. The PLA compound prepared by the invention not only has higher content of bio-group, better biodegradability and biocompatibility, but also has better water resistance because of the hydrophobic characteristic of the skeleton of the toughening monomer a (namely, the bio-oil-based derivative of the bifunctional plant containing the binary carboxyl or containing one hydroxyl and one carboxyl at the same time). |
