The Solution Properties of Poly (Phenylene ether Sulphone) in DMF (Ⅱ)

He Manj un;Wang Wei;Feng Yi East China Univ. of Chem. Tech.,Shanghai  
By wide angle light scattering and qusielastic light scattering, the molecular weightdependence of radius gyration R_G second virial coefficient A_2, radius of hydrodynamicsR_H, diffusion coefficients D_0, concentration factor of diffusion coefficient k_D ofPoly(phenylene ether sulphone) at 25℃ in the dilute solution of DMF and θ solvent havebeen measured. The results are as follow: R_G = 0.031M~(0.55) D_0(θ)= 0.906 × 10~(-4)M~(-0.5) D_0= 1.445 × 10~(-4)M~(-0.55) A_2 = 0.033M~(-0.35) k_D(θ) =-0.5M~(0.34) k_D= 2.3 × 10~(-6)M~(1.36) α_H = R_H / R_H(θ) = 0.63M~(0.05) R_H(θ) = 0.0299M~(0.5) R_H=0.0188M~(0.55)The relationship between static and dynamic molecular size, between the threekinds of expansion factor α_η, α_H and α_G, between the concertration factor of frictionalcoefficirnt and the hydrodynamic volume have also been discussed. The results are consistent with R_H / R_G= [π(v+1)(2v+1) / 3]~(1/2)(2-v)(1-v) / 2, α_η~3 =α_G~2α_H, k_F = 1.2A_2M+N_AV_H / M, k_F(θ) = N_AV_H / M.
