Soy‐based polyester: Sustainable solutions for emerging materials

Abstract

Innovative and renewable polymers and additives are the focus of increased research due to public and environmental pressure. There has been a recent uptick in interest from scientists in biobased “green” plasticizers that can be covalently bonded to replace harmful and migratory phthalate‐based plasticizers. Vegetable oils (VOs) are one of the biosources, as they are both plentiful and sustainable. This review aims to highlight the synthesis methods for soy‐based polyesters. Therefore, the chemistry of soybean oil as a polymeric material and its role in the synthesis of polyesters derived from soybeans are the primary topics of this review. This review covers the many ways in which soybean oil and its derivatives can be used to synthesize polyester, either directly or indirectly.Highlights The need for sustainable polymers is explored. Soybean oil‐based polyesters are covered. Modification and chemistry to convert soybean oil into polyester are described. Applications of soybean‐based polyesters are provided.
