Polystyrene-g-polydimethylsiloxane copolymers were prepared by using the methacryloxypropyl-polysiloxane(PDMS-MA) macromonomer technique.The structures of graft copolymers were characterized by Fourier transform infrared(FTIR) spectroscopy.The influence of molecular mass of PDMS-MA on copolymerization activity was investigated.Thermal properties of the graft copolymer were also studied.The reactivity of PDMS-MA decreased with increasing molecular mass. Meanwhile with increasing ratio of PDMS-MA to styrene
the copolymerization conversion of PDMS-MA decreased. The heat-resistance of PSt-g-PDMS was improved comparing to PSt alone.The improvement was greater when the molecular mass of PDMS-MA and its contents were increased.
