Fully Biobased Thermoset Adhesive Precursor from Itaconic Acid and Propylene Glycol.

ABSTRACT: Photocurable adhesives serve numerous practical applications, such as medical devices, electronics, sealing in LCDs, or glass bonding. This work focuses on a scalable and sustainable engineering of a new reactive precursor for photocurable adhesives, dipropylene glycol itaconate (DPG-IA). Synthesis involved Fischer esterification, with more than 98% conversion measured by convenient and affordable volumetric analyses (acid number and hydroxyl value). The product's structural verification was provided by ¹H Nuclear Magnetic Resonance (NMR) and FT-IR analysis, confirming a highly pure yield (more than 99%). Particularly, ¹H NMR and FT-IR uncovered the presence of unsaturated double bonds, which can by radically polymerized and from cured molecular structure. The rheolog
