Determination of polymer additives using analytical ...

Perhaps most challenging analytically is the determination of a non-volatile additive in a polymer matrix. Many antioxidants and light stabilizers are large molecules, sometimes small polymers, with molecular weights of several thousand. Since these macromolecules are not volatile, the thermal pre-treatments discussed above offer little help.
