A review on the synthesis of maleic anhydride based polyurethanes from renewable feedstock for different industrial applications

Polyurethanes are one of most versatile and large class of polymer because of its wide range of applications. The products of polyurethane are innovative and life-enhancing that play a unique role in making the world more sustainable and can help to solve some of the world’s biggest challenges. Most of the polyurethane products and components are durable and long lasting due to its unique chemical structure. To a large extent, the characteristics of the polyurethane are determined by the chemical nature of the building blocks and modification by the addition of the components in the backbone chain of the polymer. This review summarises the synthesis of polyurethanes using different polyols and pre-polymers from renewable feedstock and modification by maleic anhydride via different synthetic routes for various industrial applications like paints, adhesives, foam, coatings, inks, leathers, toys, automotive, packaging, dispersions, hydrogels, composites, construction etc. The objective of this review is to provide a comprehensive, informative, valuable and critical summary about the current development in the field of maleic anhydride-based polyurethanes. Graphical Abstract Generally polyurethane synthesized from Renewable as well as petrochemical sources but Polyurethane from Renewable resources is most explored transformation in polymer chemistry. This review highlights the most recent developments in the role of maleic anhydride in polyurethane synthesis from renewable feedstock/ starting material.
