Polymers derived from biomass are now a matter of the utmost importance from both commercialand academic points of view.Interpenetrating polymer networks were prepared from Castor oil, toluene 2,4diisocyanate, Acrylonitrile withsuch polymers were investigated by FTIR spectroscopy. All these IPNs films were characterised byresistance to chemical reagents, swelling behavior, mechanical studies such as tensile strength, Young’s modulus, elongation at break (%) and soil burial. Thermal stability behavior of the polymer degradationwas studied by thermogravimetric analysis (TGA), and differential thermal analysis (DTA). Dielectric ptrperties such as dielectric constant,dielectric loss and dielectric loss tangent were also estimated.The scanning electron microscopy (SEM) micrographs revealed changes in the surface morphology of thepolymers.
