Abstract

Three new reactive diluents were prepared from tung oil using a Diels-Alder reaction. The dienophiles were methacryloxypropyl trimethoxysilane (MAS), 2,2,2-trifluoroethyl methacrylate (TFM) and triallyl ether acrylate (TAEA). The chemical structures were evaluated using 1H NMR, 13C NMR, FT-IR, GPC and MALDI-TOF-MS. Spectra evidence (NMR, MS) indicated that a six-member ring were formed in all three reactions indicating a Diels-Alder adduct. The reactive diluents were formulated with a soya-based alkyd to evaluate viscosity reduction and drying time. The viscosity of alkyd was reduced up to 70% using the reactive diluents. The drying time for the autoxidative reactive diluents with alkyds were 1.8-1-7 times faster than alkyd alone.
