## Abstract Triols of molecular weights (MWs) 1000–4000, suitable for flexible foams, were prepared by transesterification of methyl esters of ricinoleic acid with trimethylol propane. These polyols were noncrystallizing, relatively low‐viscosity liquids. They were reacted with diphenylmethane diis
