Scientists performed an experiment to synthesize castor oil based hybrid polymers 
and their polyurethane urea-silica coatings. New acrylated alkoxysilane castor oil (AASCO) with hydrolysable –Si–OCH3 was synthesized from CO, maleic anhydride and 3-(Trimethoxysilyl) propyl methacrylate via free radical copolymerization method.
Characterization studies showed that castor oil modified silane based hybrid coatings had better mechanical, viscoelastic properties.
