Description
The solution properties of poly-2-methyl-5-vinylpyridine have been reported by H Sato et al., M. Miura et al. and G. B. Gechele et al. . Molecular parameters such as Flory constant, K_θ , steric factor, σ, Mark-Houwink-Sakurada constants, K' and
α, and entropy parameter, 〓, in some solvents were determined in these papers. Nevertheless,
it is meaningful to estimate , these parameters in more solvents and by a new method if it is possible.
In particular, estimation of Mark-Houwink-Sakurada equations in as many solvents as possible will make it more favorable to determine molecular weight of this polymer from viscosity measurement. In this paper, data of viscosity of poly-2-methyl-5-vinyl pyridine in seven solvents and of molecular weights for seven fractions were analyzed with usual methods. A new method for determination of Flory constant proposed by S. Gundiah was also investigated in this paper.
