英文摘要 | Poly(m-methoxyaniline) (PmMAn) with high crystallinity was synthesized by emulsion successfully. It is found that PmMAn with number-average molecular weight of 8.533?05 was obtained by the following emulsion polymerization conditions: 5°C, [mMAn]=0.119 mol.L-1, [SDS]=0.05 mol.L-1, [KPS]=6.0?0-2 mol.L-1, reaction period=5.0 h. By 1HNMR measurements, it is clearly shown that in macromolecular chain of PmMAn the ratio of benzoid to quinoid units is 4:1. XRD and SEM measurements show that PmMAn by emulsion polymerization is characterized by its high molecular crystallinity, being monoclinic with cell parameters of a=1.9436nm, b=0.6036nm, c=1.2250nm, a=90°, b=100.9° and g=90° By applying a semi-empirical quantum-mechanics AM1 in program Gaussian 98, the spatial configuration of PmMAn macromolecular chain was determined and optimized. |
