AI Technical Summary
Technical Problem
Existing bio-based biodegradable polyester materials are few in variety and have poor overall performance, making it difficult to compete with petroleum-based polyesters, especially in terms of barrier properties and heat resistance.
Method used
To develop a diethyl 2,4-oxazole dicarboxylate as a raw material for the synthesis of bio-based polyesters, an oxazole disubstituted compound with a novel structure was synthesized by reacting pyruvate compounds, urea, solvents and strong organic bases under specific conditions.
Benefits of technology
A novel green biodegradable polyester with excellent thermodynamic and biodegradable properties is provided, which significantly improves the mechanical properties of polyester materials.

Abstract
The application discloses an oxazole disubstituted compound, a preparation method and application, and the oxazole disubstituted compound has a structure shown in formula I. Most of raw materials in the oxazole diacid / ester synthesis route are synthesized by non-grain biomass, and through cyclization, deamination, carboxylation and nucleophilic substitution reaction of bromoacetone acid / ester and urea as raw materials, the oxazole diacid / ester with a novel structure is finally obtained. The obtained oxazole diacid / ester can be used as a monomer to synthesize a novel green degradable polymer. The oxazole diacid / ester has the characteristics of large structural rigidity, and can improve the mechanical properties of the polyester in the high polymer synthesis field.
