First of all, we have to know what polymer you want to estimate its crosslinking degree.

Dear all,

this question was already treated within RG. Most answers focus on the swelling behavior of the x-linked matrix. Regards

The two classical methods are equilbirium swelling (as well as determination of the gel fraction) and the rubbery modulus above Tg. NMR can also be utilized in some cases.

can you please elaborate the methods as I am very new in degree of cross linking determination

Dear all;

The basis of this area is the Flory–Rehner equation, also known as "the equilibrium swelling theory". Would you please go aver these items.

Thanks Abdelkader for the information

How can we detect degree of cross linking in protein polymers?
