| titleOfInvention | A kind of method of ester-interchange method poly butylene succinate |
| abstract | The present invention relates to synthesis of polymer material fields, disclose a kind of method of ester-interchange method poly butylene succinate, include the following steps：Dimethyl succinate, the glycol monomer containing Isosorbide-5-Nitrae butanediol and composite catalyst are subjected to esterification, 110 150 DEG C of reaction temperature, 23 hours reaction time in nitrogen atmosphere；Then polycondensation reaction is carried out under vacuum, and vacuum degree is 10 300Pa of absolute pressure, and 150 240 DEG C of reaction temperature in 23 hours reaction time, obtains poly butylene succinate.On the one hand the method for the present invention can overcome the problems, such as that polymerized monomer corrosivity is high in the prior art, on the other hand can overcome the problems, such as that by-product small molecule is more in the prior art, yield is relatively low, so as to effectively reduce poly butylene succinate production cost. |
