Synthesis of urethane acrylate macromer from palm oil-based polyol and its application as a resin for dental composite / Fadheel A. A. Alsanabani
A slightly branched urethane acrylate macromer (UAM) was synthesized by reacting palm oil-based polyol with excess amounts of polymeric methylene diphenyl diisocyanate (MDI) to form urethane prepolymer, then reacted with 2-hydroxyethyl methacrylate (HEMA) and FT-IR spectroscopy confirmed the urethan...
