Photo-polymerizable compound with isosorbide core attached by glycidyl methacrylate (Iso-GMA) was synthesized from bio-based isosorbide via two step reactions to replace bisphenol A-glycidyl methacrylate (BisGMA), and its photo-polymerizing behaviors and mechanical properties after photo-polymerization were investigated. Theviscosity ofIso-GMAwaslowerthanthatofBis-GMA, andtheglass transitiontemperature (Tg)of photo-polymerized Iso-GMA was relatively high (80.5 °C) although there was no aromatic moiety in the molecule. In addition, the adhesion properties, compressive strength, and flexural properties of photo-polymerized IsoGMA were comparable to those of Bis-GMA/TEGDMA. Bio-based Iso-GMA could be a feasible alternative to problematic Bis-GMA that widely used in a variety of applications. |
