| 中文摘要 | the compatibilization effect of poly(styrene-b-2-ethyl-2-oxazoline) diblock copolymer, p(s-b-eox), on immiscible blends of poly(2,6-dimethyl-1,4-phenylene oxide) (ppo) and poly(ethylene-co-acrylic acid) (eaa) is examined in terms of phase structure and thermal, rheological and mechanical properties, and its compatibilizing mechanism is investigated by fourier-transform infrared spectroscopy. the block copolymer, synthesized by a mechanism transformation copolymerization, is used in solution blending of ppo/eaa. scanning electron micrographs show that the blends exhibit a more regular and finer dispersion on addition of a small amount of p(s-b-eox). thermal analysis indicates that the grass transition of ppo and the lower endothermic peal; of eaa components become closer on adding p(s-b-eox), and the added diblock copolymer is mainly located at the interface between the ppo and eaa phases. the interfacial tension estimated by theological measurement is significantly reduced on addition of a small amount of p(s-b-eox). the tensile strength and elongation at break increase with the addition of the diblock copolymer for ppo-rich blends, whereas the tensile strength increases but the elongation at break decreases for eaa-rich blends. this effect is interpreted in terms of interfacial activity and the reinforcing effect of the diblock copolymer, and it is concluded that the diblock copolymer plays a role as an effective compatibilizer for ppo/eaa blends. the specific interaction between eaa and polar parts of p(s-b-eox) is mainly hydrogen bonding.
