Plage and Schulten in Ref. 23 (1990) have reported a field‐ionizaton spectrum of PHB showing peaks up to nonamers so that the possibility of applying a direct pyrolysis mass spectrometric method to obtain higher oligomers of PHAs was already known. Therefore although DCI mass spectra of PHAs were obtained by us almost simltaneously (January 1990) to our partial pyrolysis‐FAB‐MS work 13we did not publish these DCI data until their quantitative significance and the relationship between peak intensity and relative abundance of the oligomers could be completely investigated.
