POLYSORB® is an Isosorbide or 1,4-3,6 dianhydrohexitol, derivated from starch and more precisely from sorbitol, produced by Roquette. This chemical intermediate is of interest in the field of thermoplastic materials and for curable resin application. It can be used directly as a monomer or after chemical modification. Hence, isosorbide found its place as a monomer suitable for polycondensates syntheses like polyesters, polycarbonates, and thermoplastic polyurethanes.

This sustainable monomer was used by Danimer Scientific, based in Banbridge, GA – USA, in the development of a product portfolio of 100% biobased polyols (AVIO®) for polyurethane synthesis.

During this webinar, René Saint-Loup, Roquette, and Matt Terwillegar, Danimer Scientific, will share case studies on two-component coatings (2K coatings), aqueous dispersion, and casting applications. This illustrates how this biobased monomer proved to bring enhanced mechanical properties and useful improvement in chemical resistance compared to conventional fossil-fuel-based monomers.
