摘要：
Cottonseed oil (CSO) was converted into a polymerizable polyol by in-situ epoxidation and hydroxylation in the presence of water as nucleophile and sulfuric acid as catalyst. This hydroxylated CSO (HCSO) was polymerized with isophorone diisocyanate at different NCO-to-OH ratios to furnish polyurethane coatings of different composition. The mechanical properties of the resulting moisture-cured films were studied. The adhesion, abrasion resistance, impact strength, flexibility, water vapor permeability, and chemical and/or solvent and corrosion resistance of the coatings were investigated.
