Greener preparation of a flexible material based on macaw palm oil derivatives and CO2

Abstract

Carbonated macaw palm oil and maleinised macaw palm oil were reacted with five different amines to obtain renewable copolymers with a bio-based content greater than 80%. The polymerisation process is greener and reduces parallel reactions in the glycerol ester backbone. Polymerisation was completed in only 24 h at 120 °C. Polymers demonstrated flexible properties and were in a rubbery state at room temperature. The polymer using 1,6-hexanediamine-HDA showed hydrophobicity and could be a promising coating for wood that can be used for industrial applications. Moreover, all polymers were totally hydrolysed in a sodium hydroxide solution.
