S-LEC B/K is generally used in the form of solution, and the solution viscosity is an important factor.
The Degree of polymerization, followed by the relationship between the composition and the solvent are the factors that influence the solution viscosity.
Figs. 1 through 7 show the relationship between solution viscosity and resin density for the six main solvents (measured by a Brookfield type [type M] viscometer at 20'C). |
