Synthesis and Characterization of Boron Incorporated Polyester Polyol from Linseed Oil: A Sustainable Material

Polyols obtained from seed oils have established themselves as excellent building blocks of polymers, viz. polyurethanes. In this work, a novel attempt has been made to incorporate boron in the backbone of polyol [LPO] derived from linseed oil. Furthermore, LPO was treated with phthalic anhydride [PA] and boric acid [BA] (in different molar ratios) to obtain boron incorporated linseed polyester polyols [BPPEs] through solvent less synthesis process. BPPEs were characterized by spectroscopic techniques (IR,H-1 NMR and C-13 NMR) to confirm the incorporation of boron and also to elucidate their structures. Physico-chemical characterization and antibacterial behavior of BPPEs was also investigated. it is speculated that these resins may serve as excellent raw materials for adhesives, coatings and as antibacterial agents.
