SYNTHESIS AND SOLUTION CHARACTERIZATIONS OF POLYPHOSPHAZENES WITH DIFFERENT SIDE GROUPS
We have synthesized several kinds of polyphosphazenes through ring-opening polymerization, and later by reacting with sodium alkoxide and sodium phenolate. These polymers have high M_w up to 5×10~6. Then they were studied by gel permeation chromatography (GPC) coupled with multidetectors including a viscometer、 a multiangle laser light scattering (MALLS) andin and a 90° angle dynamic laser light scattering in THF(with 0.1% tetra-nbutylammonium bromide) at 35℃. The results showed that hydrophobic polymers polydiphenoxyphosphazene(PDPP) and polydiethoxyphosphazene(PDEP) had the same Rg/Rh=1.80. The scaling relations of these polymers were
