The complexes were characterized by elemental analysis, XRD, UV, IR and 1H NMR. The crystal structure of the complexes belongs to triclinic system with the cell parameters: a =1 297 1 nm, b =1 621 0 nm, c =2 047 0 nm, α =85 40°, β =88 80°, γ =99 00° for [CuC 30 H 26 N 2O 4·0 5H 2O]; a =1 300 2 nm, b =1 882 6 nm, c =2 127 4 nm, α =86 47°, β =89 23°, γ =99 11° for [NiC 30 H 26 N 2O 4]; a =1 286 5 nm, b =1 596 1 nm, c =2 056 9 nm, α =87 95°, β =93 17°, γ =98 21° for [CoC 30 H 26 N 2O 4], respectively. The N and O atoms in the complexes appeared coordinated directly to the metal ions. A quadridentate chelate may be formed.展开更多

Storage stability klow behavior of the latexes,morphology of the obtained latex particles, dynamic viscoelastic behavior, tensilestrength and water resistance properties of the resulted copolymers were investigated.The experimental results show that with the addition of AHPS, stability of the emulsionis greatly improved that there appears no apparent precipitation dunring thepolymerization and storage at room temperature for 6 months and at -10℃ for fourmonths. Flow of the latexes follows the Bingham body laws, diameter of the latexparticles is about 0.6μn, of which is larger than that of by conventional emulsionpolymerization(0.12μm). In addition, not only water resistance of the copolymersobtained by emulsifier-free emulsion polymerization is greatly improved, but alsotensile strength is obviously enhanced.展开更多
