There are multiple methods to estimate the crosslinking density of a polymer. However, I have not seen an example of using these methods to calculate the crosslinking density of a polymer that is used in a composite (and not pure).
Is there any way to estimate that using the rheological methods and probably using the volume fraction of the polymer?
Have you seen some formula for this that is published?
Thank you!
PS. I do not know the molecular or molecule's weight between two crosslinks, either - unless there is a method to calculate these from the rheological data or something similar.
Dear Siavash Sarrafan, swelling test is the most used technique. Most techniques are reviewed in the following paper. My Regards
