| 英文摘要 | Polydichlorophosphazene was synthesized through ring-opening polymerization of phosphonitrilic chloride trimer at high temperature. The two polyphosphazene samples with different side groups were synthesized through reaction of polydichlorophosphazene with different sodium alkoxides or sodium phenolates. These polymers have high M(w) up to 3 x10(6) and are studied with gel permeation chromatography (GPC) coupled with multidetectors including refractive index detector, viscometer, multi-angle laser light scattering (MALLS) in THE with 0. 1% tetra-n-butylammonium bromide at 35 degrees C. R(g)/R(h) of polydiphenoxyphosphazene (PDPP) and polydiethoxyphosphazene (PDEP) are 2. 17 and 2.23. Their scaling relations are [eta] = 9. 10 x 10(-2) M(0.58) and R(g,x) = 1.62 x 10(-2) M(w) (0.58) for PDEP while [eta] = 1.71 x 10(-2) M(w) (0.64) and R(g,z) = 0.80 x 10(-2) M(w) (0.60) for PDPP. It indicates that both polyphosphazenes exhibit a random coil conformation in THF. |
