Representation of selected characterization data of PEtOx-A DP10. (A) 1H NMR spectrum of PEtOx-A DP10 (CDCl3, 300 MHz) and assignment of the signals to schematic representation of the structure. (B) Zoom into the most abundant m/z region of the matrix-assisted laser desorption ionization with time of flight (MALDI-TOF) mass spectrum of PEtOx-A DP10 (trans-2-[3-(4-tert-butylphenyl)-2-methyl-2-propenylidene] (DCTB) and sodium iodide (NaI)). The inset displays the overlay of the measured and calculated isotopic pattern for the given molecular formula. The full spectrum is depicted in the supporting information (Figure A2a in Appendix A). (C) Size exclusion chromatography (SEC) elugrams of PEtOx-A DP10 and PEtOx-A DP50 (N,N-dimethylacetamide (DMAc), 0.21% LiCl, refractive index (RI) detection). For additional information, see Table 1.
