From Biomass to Bio‐Based Polymers: Exploitation of Vanillic Acid for the Design of New Copolymers with Tunable Properties

Vanillic acid represents a potentially interesting bio-based building block for the production of new aliphatic-aromatic polymers, characterized by thermal properties similar to those analogous terephthalic polyesters. However, poly(ethylene vanillate) proved be very brittle material, probably due high degree crystallinity, and, then, not suitable melt processing. Therefore, synthesis copolymers, based on vanillic and pentadecalactone is considered as strategy obtain polymeric materials with low tunable better performances. The these fully random copolymers was successful. have been studied in order correlate chemical structure final polymers processable films were obtained, suggesting possible applications sustainable flexible packaging.
