were prepared by in situ copolymerization. Light transimissivity measurement
fluorescence
DSC techniques were used to study the miscibility
interactions of two components and structural transitions. The results indicate that P(MMA MAA) and PPSQ are completely miscible on a small scale of 200nm because of some strong hydrogen bonding interactions between molecules of P(MMA MAA) and PPSQ when the blends contain a small amount of PPSQ and that PPSQ with a low molecular weight has better miscibility with P(MMA-MAA)than that of PPSQ with higher Mw.Although compositions of the blends has little influence on Tg
Tf
of the blends almost increase with an increase of PPSQ content (PPSQ≤1%).Ball hardness and impact strength of all blend samples were also measured.
