Castor oil-based polyfunctional acrylate monomers: Synthesis and utilization in UV-curable materials

A new polyfunctional acrylate monomer (COPERAA) was synthesized from castor oil and utilized as a sustainable reactive diluent for UV-curable materials. Firstly, experimental conditions for the synthesis of the monomer were optimized and its chemical structures were confirmed by FT-IR, 1H NMR, and ESI–MS. Subsequently, the effect of COPERAA on biobased content, viscosity, and volumetric shrinkage of the obtained AESO resins were studied. After...
