Copolymerization of St and St-POSS with and without 4-MeSt was carried out with half-titanocenes of Cp*TiCl3 catalyst and MMAO cocatalyst. The activity of catalyst and St-POSS content increased by the addition of 4-MeSt as the 3 rd monomer. The characteristic crystalline peak of St/St-POSS copolymer  was altered by incorporating of 4-MeSt. With increasing 4-MeSt contents, the glass transition temperature of the polymers increased and the  thermal stability was improved. The molecular weight and PDI of the polymers were not changed significantly with the incorporation of 4-MeSt.
