Abstract

The structures of two homologous series of oligo[(2‐hydroxy‐1,3‐phenylene)methylene]s completely esterified with methacrylic acid, were spectroscopically analysed. The molar decadal absorption coefficients of ultraviolet absorption maxima of the two homologous series confirm Hunter's relation. The vinylidene, ester, and substitution bands of the infrared spectra as well as the mass spectra agree with the accepted structures. The ^1^H NMR spectra permit to differentiate between exterior and interior groups of the molecules.
