The maleicacid-castoroilmonoester (MACO) was synthesized and was used as monomer to synthesize a newpotentiallyenvironmentallyfriendlycopolymerofstyrene and MACO (poly-St/MACO) by suspension polymerization. Under the appropriate conditions, the poly-St/MACO with yield of 81%, number average molecular weight of 44100?g/mol, and molecular weight distribution of 1.5 could be obtained. The chemical structures of the MACO and resulting copolymer were confirmed by Mass Spectrometry Infrared Spectroscopy and Nuclear Magnetic Resonance Spectroscopy H. The results of thermogravimetric analysis and biodegradation test showed the poly-St/MACO can be used as a newpotentiallyenvironmentallyfriendly material with excellent thermal stability.
