Synthesis and characterization of hydrolysis palm kernel oil-based polyurethane / Nursyashabillah Nor

This study was conducted to investigate the hydrolysis reaction of rigid palmbased polyurethane. Rigid polyurethane (PU) was synthesized by using monoester-OH kernel oil (polyol). The resulting PU sample was immersed in an aqueous solution of sodium hydroxide (NaOH) concentrations of 0%, 10%, 20%, 3...
