Polyurethane films were prepared from the reaction of cardanollignins (CL) with a different cardanolpignin ratio and toluene diisocyanate. The crosslink density, the glass transition temperature and the mechanical properties of the obtained films were also determined. The increase of cardanol conten

## 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

Almtract--New polyesters were prepared by reacting 2,6-di(4-hydroxystyryl)pyridine (DHSP) with terephthaloyl or adipoyl chloride utilizing the interfacial polycondensation method. In addition, new polyurethanes were prepared by reaction of DHSP with a diisocyanate such as tolylene diisocyanate, meth
