溶液中高分子尺寸的测定,广泛用于研究高分子链在溶液中的形态。高分子在稀溶液里的一些性质如表观粘度、扩散速度等都取决于溶液中高分子尺寸的大小。本文推荐一种粘度计,采用粘度法测得高分子溶液的特性粘数,从而计算高分子链的尺寸。原理溶液中高分子的形状和尺寸不仅与其本身的结构有关,还与溶剂性质、溶液浓度以及实
The determination of polymer size in solution is widely used to study the morphology of polymer chains in solution. Some properties of polymers in dilute solution such as apparent viscosity, diffusion rate, etc., are dependent on the size of the polymer solution size. In this paper, we recommend a viscometer to measure the intrinsic viscosity of the polymer solution by the viscosity method to calculate the size of the polymer chain. Principle The shape and size of the polymer in solution are not only related to its own structure, but also to the nature of the solvent, the concentration of the solution,
