Abstract
Direct pyrolysis mass spectrometry (DPMS) has been applied to poly(p-x ylylene) (PPX) and poly(hydroxybutyrate) (PHB) samples. The validity o f a mathematical model for pyrolytic behaviour was tested using PPX an d then applied to PHB. Simple cleavage at an ester bond has been shown to be the most probable process in the latter. Examination of a rando m copolymer of PHB with 20% hydroxyvalerate (HV) shows that the latter behaves pyrolytically in a similar manner to PHB itself. DPMS can be used to detect very low levels of a second monomer in a polymer sample .
