| 英文摘要 | In situ polymerization and in situ compatibilization was adopted for preparation of ternary PA6/PS-g-PA6/PS blends by means of successive polymerization of styrene, with TMI and epsilon-caprolactam, via free radical copolymerization and anionic ring-opening polymerization, respectively. Copolymer poly(St-g-TMI), the chain of which bears isocyanate (-NCO), acts as a macroactivator to initiate PA6 chain growth from the PS chain and graft copolymer of PS-g-PA6 and pure PA6 form, simultaneously. The effect of the macroactivator poly(St-g-TMI) on the phase morphology was investigated in detail, using scanning electron microscopy. In case of blends with higher content of PS-g-PA6 copolymer, copolymer nanoparticles coexisting with the PS formed the matrix, in which PA6 microspheres were dispersed evenly as minor phase. The content of the compositions (homopolystyrene, homopolyamide 6, and PS-g-PA6) of the blends were determined by selective solvent extraction technique. The mechanical properties of PA6/PS-g-PA6/PS blends were better than that of PA6/PS blends. Especially for the blends T10 with lower PS-g-PA6 copolymer content, both the flexural strength and flexural modulus showed significantly improving because of the improved interfacial adhesion between PS and PA6.
