Biobased Polyols Using Thiol-Ene Chemistry for Rigid Polyurethane Foams with Enhanced...

Biobased polyol was synthesized using 1-thioglycerol and limonene, an extract of orange peel, via thiol-ene chemistry as an alternative to petrochemical-based polyol for preparation of rigid polyurethane foams (RPFs). Fire-retardant polyurethane foams were prepared by addition of different amounts of dimethyl methyl phosphonate (DMMP) in the...

Synthesis of fluorinated polycarbonate-based polyurethane acrylate for UV-curable coatings

Fluorinated polycarbonate-based UV-curable polyurethane acrylate (F-PCUA) was synthesized by incorporating 1H, 1H, 2H, 2H-Perfluoro-1-octanol to the end of polycarbonate-based PUA chains. The structure of F-PCUA was determined by 1H-NMR, 19F-NMR, and FTIR analyses. The physical, surface, and thermal properties of F-PCUA were also examined. The...
