Abstract
Nine fractionated samples of poly-2-methyl-5-vinylpyridine (PMVP) have been investigated by viscosity and light-scattering measurements at 25°C. In the range of the molecular weights from about 1×105 to 1×106, the following relationship between the intrinsic viscosity and the molecular weight in methanol has been obtained: [η] =0.80×10−4Mw0.76. The unperturbed molecular dimensions have been obtained using the recent theories of the solution behavior of high polymers. The results have been compared with those of other vinylpyridine polymers and polystyrene, and it has been found that the degree of the extension of PMVP is almost the same as those of the other polymers.
