| titleOfInvention | Macromolecular nucleating agent for rapid crystallization of polylactic acid and use method thereof |
| abstract | The invention belongs to the technical field of high polymer materials, and particularly relates to a macromolecular nucleating agent for rapid crystallization of polylactic acid and a use method thereof. The structural formula of the macromolecular nucleating agent is as follows: n is more than or equal to 5 and less than or equal to 5000; wherein, R is 1 And R 3 Is an aliphatic main chain structure; r 2 Is a side chain structure with an ester functional group, R 4 Is a main chain structure with thioether. The macromolecular nucleating agent can be added into a polylactic acid matrix, the addition amount is 0-2 wt%, and the polylactic acid is rapidly crystallized by a melt blending or solution blending method to prepare the polylactic acid resin. The macromolecular nucleating agent can greatly improve the crystallization rate of the polylactic acid on the basis of adding a small amount of the macromolecular nucleating agent. The addition amount of the nucleating agent in the polylactic acid matrix is small, and the compatibility and the dispersibility between the nucleating agent and the polylactic acid matrix are good, so that the influence of the use of the nucleating agent on the mechanical property and the processing characteristic of the polylactic acid material is small. |
