Poly(butyl cyanoacrylate) was synthesised using triphenylphosphane and pyridine initiators. Matrix‐assisted laser desorption/ionisation time of flight mass spectrometry and NMR spectroscopy were used to confirm that the initiator remains as a chain end group. The prepared polymers were subjected to thermal degradation and re‐analysed with results that show the loss of the initiator end group for the pyridine‐initiated polymer, but not for that initiated with triphenylphosphane. Pyrolysis gas chromatography‐mass spectrometry was used to observe the presence of the pyridine initiator in the volatile degradation products.
