| 中文摘要 | an extended goldman-shen pulse sequence was used to observe indirectly the proton spin diffusion in the blends of polystyrene (ps) with poly(2,6-dimethyl-1,4-phenylene oxides) (ppo). the results indicate that the average distance between ps and ppo is less than 5 angstrom in the intimately mixed phase, but there are heterogeneous domains on a 100-angstrom scale. the data of spin relaxation of carbons, t1(c), for homopolymers and their blends suggest that there is a strong pi-pi electron conjugation interaction between the aromatic rings of ps and those of ppo, while the aromatic rings of ppo drive the aromatic rings of ps to move cooperatively. it is the cooperative motion that markedly improves the impact strength of ps. |
