Global Trends for kp? Expanding the Frontier of Ester Side Chain Topography in Acrylates and Methacrylates Alexander P. Haehnel, Maria Schneider-Baumann, Kai U. Hiltebrandt, Andrea M. Misske, Christopher Barner-Kowollik* Exemplary SEC chromatograms are shown for each monomer at 4 temperatures as well as tables with the exact samples conditions. Furthermore, the temperature dependent density curves for each monomer and the differential scanning calorimetry (DSC) curves are provided and the results are summarized in Table 1 in the main article. Additionally, as a typical example, the success of the fractionation – required for the MHKS parameter determination – is demonstrated for pBeMA as polymer system; the data points incorporated into the individual MHKS plots of each monomer are stated in Table S9. Furthermore, exemplary triple detector SEC traces are shown for each polymer system.

Figure S1. Exemplary molecular weight distributions (red dotted lines) and their first derivative (solid black lines) of SMA in bulk (upper four diagrams) and in 1 molar solution in butyl acetate (lower four diagrams). The sample specific conditions are displayed in the diagrams and also collated in Table S1 for bulk and in Table S2 for 1 molar solution in butyl acetate. The typical PLP structure is observed for all samples.

Figure S2. Exemplary molecular weight distributions (red dotted lines) and their first derivative (solid black lines) of BeMA in bulk (upper four diagrams) and in 1 molar solution in butyl acetate (lower four diagrams). The sample specific conditions are displayed in the diagrams and also collated in Table S3 for bulk and in Table S4 for 1 molar solution in butyl acetate. The typical PLP structure is observed for all samples.

The glass transition temperatures are summarized in Table 1. The glass transition effect of PHMA is relatively less pronounced, however the handling experiences (brittle/hard below 20°C, chewy/sticky above 20°C) underpin the measured effect.

Typical fractions of a PLP polymer sample for the MHKS parameter
determination procedure via triple detector SEC. The black, bold and solid line corresponds to the complete pBeMA (PDI = 13.35) polymer sample, produced under various PLP conditions (i.e. various PLP samples were combined and the polymer isolated), which was used for the fractionation. The various colored dashed lines correspond to the individual fractions obtained via a SEC fractionation as described in the Experimental Section. The PDI values of the obtained fractions range between 1.05 and 1.25.
