An attempt was made to construct the most reliable database on stereoregular polyacrylonitrile (PAN) solutions for further analysis. For this purpose, literature data, reported for these 25 years by Kamicle and his coworkers at Asahi, on light scattering and limiting viscosity number [η] of PAN with various tacticity (meso-meso triad content of 26-75%) dissolved in solvents including aq. nitric acid with concentration 51-80% were utilized. The molecular weight dependences of [η]([η] = K_mM_w^a; M_w: weight-average molecular weight) and of the radius of gyration <S^2>_z^<1/2> = (<S^2>_z^<1/2> = K_γM_ω^γ) wene evaluated for each polymer solutions. Flory's theta solvent compositions were determined experimentally as the solution, in which the second virial coefficient A_2 vanishes a = γ = 0.5 holds in Flory solvents. The unperturbed chain dimension A and Flory viscosity parameter φ_0 were directly determined at Flory condition. |
