Document Type and Number:
WIPO Patent Application WO/2021/090825
Kind Code:
A1
Abstract:
[Problem] To provide a polyester compound derived from biomass, the polyester compound being extremely useful as a rubber material and an adhesive material, and having a multiple bond within a molecule. [Solution] In the present invention, an ester compound comprising hydroxycinnamic acids and fatty acids is synthesized, and a polycondensation reaction is carried out using this ester compound as a monomer, to efficiently produce a polyester compound in which cinnamic acids and recinoleic acid derivatives are alternately linked to each other. For example, an ester compound represented by general formula (1) is produced. In the formula, substituents R1 and R2 each represent a hydrogen atom or a methoxy group. Substituent R3 represents an alkyl group or an alkenyl group. n is an integer between 10 and 100.
