| titleOfInvention | A kind of preparation method of degradable oxyacetic acid copolyesters |
| abstract | The invention discloses a kind of preparation method of degradable oxyacetic acid copolyesters, the present invention's utilize oxyacetic acid, hexanodioic acid and ethylene glycol to carry out oxyacetic acid copolyesters that polycondensation obtains high molecular, owing to adopting direct condensation, makes whole technical process short, omnidistance side reaction is few, and production energy consumption is low; And with oxyacetic acid, hexanodioic acid and ethylene glycol for raw material, raw materials cost is low, make the production cost of the oxyacetic acid copolyesters finally obtained lower.And obtained oxyacetic acid copolyesters intrinsic viscosity is higher, have good mechanical property, Practical Performance is better.In addition, because oxyacetic acid copolyesters of the present invention all adopts biodegradable monomer polycondensation to form, thus there is biodegradability completely, and in preparation process, do not use the catalyzer such as tin class and plumbous class that toxicity is larger, thus to human non-toxic's evil, be a kind of macromolecular material of safety and environmental protection. |
