How to determine molecular size?
Thread Content
How can we know what the molecular diameter of some high-molecular-weight organic compounds is?
What is the poster trying to achieve with this? We generally use the melt flow ratio to measure the molecular weight distribution of a material, that is, the ratio of the melt index of the material measured at pressures of 21.6 KG and 2.16 KG!
Is it okay to use viscosity to calculate the molecular weight? :o n=0.8*10(-4)*M(0.65); note that the numbers in parentheses represent exponents, with n denoting viscosity and M denoting molecular weight.
There is indeed no parameter indicating the polymer diameter at the moment. Mainly, the client needs to clarify which properties of the polymer are being characterized.
For example, some surfactants, hexadecylpyridinium chloride
