Major effects known from injection molding polyamides are chain scissions and changes of chemical structure due to autoxidation as well as branching or cross linking as a result of macro radical recombination (Ehrenstein et al, 2004; Schnabel, 1981).

Much of the autoxidation can be prevented by protecting samples from light and completing the extraction and derivatization rapidly.
