Abstract
A novel compound bearing urethane linkage of formula as shown herebelow, which is an adduct of ricinoleic ester and isocyanate, useful as a plasticizer for polyvinylchloride (PVC) and a process for the preparing the compound bearing urethane linkage by reacting fatty acid esters bearing hydroxyl groups with an organic isocyanate in the presence of a catalyst at a temperature in the range of 30.degree.-100.degree. C. ##STR1## Wherein Ar= ##STR2##
Claims1
