Reactions taking place between phenylglycidylether (PGE) and pip‐eridine (PP), and PGE and 1‐( N ‐piperidinyl)‐3‐phenoxy‐2‐propanol (TAA) were followed by means of nuclear magnetic resonance (NMR) spectroscopy. For an equimolar mixture of PGE and PP, reaction was limited to the addition of PP to PGE. The structure of this reaction product (TAA) was determined by 1 H and 13 C NMR spectroscopy. In the presence of an excess of PGE homopolymerization occurred. Two different oligomers (P 1 and P 2 ) were obtained as reaction products and their structures were studied. During the progress of the reaction, the molar ratio [P 1 ]/[P 2 ] was measured and as a result [P 2 ] was greater than [P 1 ] over the entire reaction time. This finding was explained by the importance of the transfer reaction in the homopolymerization of PGE. When an excess of PGE was used in the PGE–TAA reaction, the product was similar to that of the PGE–PP reaction. © of SCI.
