| titleOfInvention | Method for improving crystallization performance of biodegradable aliphatic aromatic copolyester |
| abstract | The invention relates to a method for improving the crystallization performance of biodegradable aliphatic aromatic copolyester, which mainly solves the technical problems of low crystallization temperature and low crystallization speed of the biodegradable aliphatic aromatic copolyester in the prior art. The method comprises the following steps: adding raw materials, catalysts, branching agents and other auxiliaries into a reactor, and carrying out esterification and polycondensation to obtain an aliphatic aromatic copolyester melt; directly shearing and cooling the obtained aliphatic aromatic copolyester melt, or cooling and granulating the obtained aliphatic aromatic copolyester melt, and then melting, shearing and cooling to obtain the aliphatic aromatic copolyester with high crystallization performance; wherein the shear has a maximum continuous shear rate of not less than 50s ‑1 The technical scheme that the product of the maximum continuous shearing rate and the continuous shearing time is not less than 10 better solves the problem and can be applied to the production of biodegradable aliphatic aromatic copolyester materials at high crystallization temperature. |
