摘要：

interactions in bisphenol-A polycarbonate/poly(styrene-co-methacrylic acid) (PC/P(S-MAA) blends, which show UCST phase transition and Miscibility Valley phenomena in temperature-copolymer composition plant, were investigated by Fourier transform infrared (FT-IR) spectroscopy. It was found that methacrylic acid (MAA) units in poly(styrene-co-methacrylic acid) (P(S-MAA) formed associated dimers at low temperature and the dimer dissociated with elevating temperature. Since the temperature dissociating associated dimer of MAA units was corresponding to phase transition temperature in PC/P(S-MAA) blends, the UCST phase behavior would be caused by association-dissociation in NAA units.
