摘要: The viscosity, osmotic pressure and light-scattering of a series 14 fractions poly-2-vinylpyridine in various solvents have been measured. following results obtained: constants, Kw′ v, the Mark-Houwink equation determined for solutions of: (a) 92.01 weight per cent ethanol, (b) methanol, (c) dimethylformamide, (d) benzene (e) dioxane as follows:(a) [η]=1.22×10−4Mw0.73 (d) [η]=1.70×104Mw0.64(b) [η]=1.13×104Mw0.73 (e) [η]=3.09×104Mw0.58(c) [η]=147×10−4Mw0.67The molecular polymers ranged from 3.4×104 to 93×104, while viscosity was measured at 25±0.01°C. constant, K′ case homogeneous has calculated assuming exponential- logarithmic normal-type distribution functions each fraction. Flory K, defined [η]θ=KM1⁄2 found by method Fixman Krigbaum be: (8.7±1.0)×10−4 25°C. K value also be (9.1±...
