- Agro based raw materials such as polyol modified castor oil polyurethanes and cardanol based dyes were used to synthesize interpenetrating polymer networks. Such polymers prepared using benzoyl peroxides as initiator and ethylene glycol dimethacrylate as cross-linker and not studied intensively were characterized by FTIR study and various thermal technique such as TGA, DTG and DTA. The kinetic parameters such as activation energy (Ea) and order (n) of reaction were calculated by using the Freeman-Anderson method. The effects of change in PU/CD weight ratio and NCO/OH molar ratio of polyurethanes on thermal properties of such polymers were studied.
