| titleOfInvention | The semi continuous preparation method of Biodegradable polyester resin |
| abstract | The present invention provides a kind of semi continuous preparation method of Biodegradable polyester resin, including：(I) step, at least one dihydroxylic alcohols and catalyst at least one dicarboxylic acids, the aliphatic dihydroxy alcohol in aliphatic dicarboxylic acid and aromatic dicarboxylic acid are put into the first batch reactor carries out esterification by dicarboxylic acids and dihydroxylic alcohols；(II) step, is transplanted on the second batch reactor, so as to carry out polycondensation reaction by the esterification reaction product obtained from (I) step；(III) step, is transplanted on the polycondensation product of the molten condition obtained from (II) step surge tank and is stored；And (IV) step, the polycondensation product and chain extender in surge tank are supplied to flow reactor, so as to carry out chain extending reaction.Biodegradable polyester resin preparation method of the invention is used and uses batch polymerization processes and the semi continuous preparation method of continous way chain extending reaction technique, it is thus possible to eliminate the problem occurred in the case where each technique is used alone. |
