The negative secondary ion mass spectra of the four isomeric poly(butylmethacrylates) are presented. The four isoineric butanolate anions which are formed fragment in a way which is specific for each isomer. In all cases, α,β‐elimination (relative to the oxygen atom) of suhstituents from the parent anions plays an important role. The mechanism of elimination of alkanes and molecular hydrogen from the butanolate anions is explained by the formation of hydride or alkyl anions from the α‐position of the butanolate anions. These newly generated ions abstract a proton or, with less probability, an aikyl subsrituent from the β‐position.
