Poly(vinyl acetates) with either isopropylol or (1‐hydroxyethyl)‐2‐oxyisopropanyl end groups were analysed by tandem mass spectrometry using a quadrupole‐time‐of‐flight (Q‐TOF) instrument. Random scission along the polymer backbone was not observed. Instead the initial scissions were derived from the cleavage of end‐group species. The resultant macrocations were subject to further elimination reactions that eventually produced polyene macrocations. A smaller fraction of the initial macrocations also reacted by loss of ketene and this reaction produced macrocations containing vinyl alcohol units. Copyright © 2004 John Wiley & Sons, Ltd.
