Abstractp‐Cresol and eight oligo[(hydroxyphenylene)methylene] compounds1b–eand4a–dcould be esterified with good yields with acryloyl chloride or propionyl chloride, respectively, in the presence of triethylamine. The simple and multiple acrylates and propionates were characterized by determination of their molar masses, elemental analyses, hydrogenation of the CC double bonds in the acrylate groups, and by their IR‐ and UV‐spectra. No steric hindrance could be ascertained. Acrylates with more than three phenolic units in their molecules were found to have a range of melting, whereas all the propionates possess sharp melting points. This can be explained by polymerization of the acrylates which proceeds at room temperature without changing the appearance of the sample. The decadic molar absorption coefficients from the UV‐spectra of the different homologous series were found to be proportional to the number of the phenolic units in thei
