A functional polyester elastomer and a method for synthesizing the same
A one-step synthesis method for functional polyester elastomers was developed, utilizing short-chain, low-molecular-weight diols and rigid cyclic diols to form a microphase separation structure. This method solves the problems of complex synthesis and low molecular weight of existing thermoplastic elastomers, and enables the preparation of high-molecular-weight and multifunctional materials.

AI Technical Summary
Existing methods for synthesizing thermoplastic elastomers are complex, resulting in low molecular weights, poor mechanical properties, and limited functionality.
A one-step synthesis method is adopted, in which short-chain low molecular weight diols are first added to the reactor, followed by rigid cyclic diols, multifunctional aromatic or aliphatic esters, photo-induced functional monomers, catalysts and antioxidants, and a temperature-step heating reaction is carried out to form functional polyester elastomers.
It increases the molecular weight of the polymer, forms a microphase separation structure and a three-dimensional network, improves the heat distortion temperature, solvent resistance and wear resistance of the material, and endows the material with reversible mechanical properties and shape memory function.
