4,4'-偶氮二[4-氰基戊酰(对-二甲氨基)苯胺]作为引发剂的嵌段共聚物合成 总被引:4,自引:0,他引:4
his paper describes a new polyfimctional inihator, 4,4'-azobis[4-cyanopentanoyl (p-dimethylandno)anilide] (ACPDA), for the the radical polymerization. It was obtained by the rcaction of 4,4'-azobis(4-cyanopentanoyl chloride) with p-amino-N, N-dimethylaniline' ACPDA contains two reaction centres with different reactvities that are azo-group and N, N-dimethylaniline-group. By the controlled different conditions this initator can be utilized to make block polymers. 相似文献

The magnetization of ternary metal Prussian blue analogues A1xA21-x B,formed by three different sublattices A1,A2 and B,is studied by using the effective-field theory with self-spin correlations.Effects of the mole fraction x,the anisotropy and the transverse magnetic field on the magnetization are discussed. 相似文献

The quantum fluctuations of a three-layer Heisenberg model with six sublattices are studied by the retarded Green’s function method and the spin-wave theory.The effects of anisotropy on the quantum fluctuations at zero temperature are discussed.The results show that the interlayer anisotropy plays an important role in balancing the quantum competitions. 相似文献
