Abstract

S. Sridevi and P. Raghunath Rao*

Copolymers of Acrylonitrile with Isobornyl acrylate (IBA) and Isobornyl Methacrylate (IBM) were synthesized by free radical polymerization using AIBN as initiator in dimethyl formamide (DMF) at 60 ± 1°C. Thermo gravimetric analysis of the copolymers was performed and their thermal stabilities were studied. Thermal stability of IBM copolymers is found to be more than that of IBA copolymers. The dielectric properties of the copoymers were studied. The dielectric loss of the copolymers is found to be shifting to a higher temperature from acrylate to methacrylate copolymers.
