Analysis of Additives in Polymer Extract Solution Using LCMS-IT-TOF

It is known that the additives added to polymer materials can vary even for identical types of products, depending on the grade or manufac-
turer. Therefore, identifying the additives in polymer materials provides important information for investigating the performance of competi-
tor products or improving one's own products.
Based on the formula (C28H52N2O4) predicted for peak A using Formula Predictor and accurate masses obtained from MS, MS/MS, and
MS/MS/MS analysis, peak A presumably corresponds to decanedoic acid bis (2,2,6,6-tetramethyl-4-piperidyl) ester.
