COMPATIBLE CHARACTERISTICS OF POLYETHERETHERKETON/POLYARYLETHERSULFON WITH CARDO GROUP BLENDS
聚醚醚酮与酚酞型聚芳醚砜共混物的相容性特征

By using DSC,TBA(Torsional Braid Analysis)and FTIR,the compatiblecharacteristics of polyetheretherketon(PEEK)/Polyarylethersulfon with cardo group(PES-C)blends have been studied.The results show that PEEK and PES-C are partiallycompatible,and the compatible extent of the blends is related to its thermal history.Whenthe compatible extent is high,two T_g of the blends move toward each other,and the glasstransition in PES-C-rich part broadens.The partial compatibility of PEEK/PES-Cblends was confirmed by the interaction between PEEK and PES-C molecules.
