In view of the alarming rate at which the petroleum is getting depleted, there is an increased drive for developing resources based on renewable resources that are easily convertible to useful industrial raw materials. In this perspective, we have explored the possibility of deriving value added precursors for deriving polymeric adhesives from castor oil. The rich chemistry of the castor oil (CO) makes it a good starting material for a wide range of application. The double bond C=C present in raw castor oil can be converted to oxirane groups by epoxidation of CO by insitu generated performic acid. The so formed polymeric adhesives shows good peel adhesion properties and mechanical strength.
