| titleOfInvention | Two steps of high-performance poly copolyether ester elastomer feed intake synthetic method |
| abstract | The invention discloses two steps of a kind of high-performance poly copolyether ester elastomer to feed intake synthetic method, including: dioctyl phthalate, dihydroxylic alcohols and catalyst mix are reacted, obtain polyester hard section, by described polyester hard section and polyether polyol, antioxidant and catalyst reaction, it is thus achieved that described high-performance poly copolyether ester elastomer. Present invention process is simple, easily operated, controllability is good, safety and environmental protection, with low cost, not only avoid the inhibitory action of esterification during polyester hard section is synthesized by polyether polyol, more decrease the thermal degradation side reaction that polyether polyol causes because reacting for a long time at relatively high temperatures, thereby is achieved that molecular weight height, polyester hard section be controlled with polyester soft segment molecular weight and the polyester elastomer of excellent performance. |
