The capabilities of ATD-GC/MS to provide a routine diagnostic tool for fingerprinting polymers (w.r.t. type, origin, process history, etc.) have been investigated for an integrated series of polyolefins distinguished by different levels of tertiary hydrogen. The approach relies on a compositional analysis of volatile components trapped within a polymer, which in this case was performed for: HDPE, LDPE, LLDPE and PP homo- and copolymers in powdered and pelletised form. A 10-min desorption cycle followed by ca. 20 min of GC analysis provided the basis for this study which examined the wealth of detector (MS) data for diagnostic features. Both total- and selected-ion outputs were compared, and features characteristic of polymer type, manufacturing route (e.g. stereoregular vs random), and of thermal affects in processing were recognised. One sample from an extended period of service was also examined, and the chemically-induced changes were rationalised in terms of both thermal (isomerisation) and oxidative effects.
