| titleOfInvention | Low melting point thermoplastic polyester elastomer and preparation method thereof |
| abstract | The invention relates to the technical field of polyester elastomer preparation, and relates to a low-melting point thermoplastic polyester elastomer and a preparation method thereof. The former is obtained by the following method: the first step: esterification, adding a required amount of aromatic dibasic acid to , 1,4-butanediol, polytetramethylene ether glycol and the fourth component are mixed, and esterification is carried out under the effect of catalyst one to obtain esterification; The second step: pre-shrinkage, add in the esterification The catalyst 2, the antioxidant and the small molecular polyol undergo a pre-condensation reaction to obtain a prepolymer; the third step: final condensation, the prepolymer is subjected to a polycondensation reaction to obtain a low-melting point thermoplastic polyester elastomer. The low-melting point thermoplastic polyester elastomer of the present invention is synthesized by one-step polymerization, the process is simple, and the operation is convenient. , Wide range of applications, flexible and adjustable product indicators, can meet the processing needs of different application products. |
