The new polyol architecture from olive oil and its application in the soft transparent polyurethane coating
View through CrossRef
Abstract
A renewable, green and scalable polyacrylic polyol (PAMO) was synthesized from olive oil (OO) and applied as a polyol in the preparation of transparent polyurethane coating. To prepare PAMO, the olive oil was first methanolized using methanol and methyl oleate (MO) was obtained. Then MO epoxidized by formic acid and hydrogen peroxide. The epoxidized methyl oleate (EMO) was ring-opened using acrylic acid (AA) with excellent yield. The PAMO was prepared by solution free radical polymerization. The chemical structures of synthesized monomer and polymer were verified by FT-IR, 1HNMR, and gel permination chromatography (GPC). The different thermoset aliphatic transparent polyurethane coating was obtained using the reaction between synthesized polyol and Isophorone diisocyanate (IPDI), Desmodur N3390 and Desmodur Z4470. The best results were obtained with Desmodur Z4470 as curing agent. The new polyol architecture has appeared as a new class of polyacrylic polyol and transparent polyurethane coating.
