Results of a study testing the stability of the ether ClSi ATRP initiator in the reaction solvent. PC1 vs PC2 scores plot (A) with corresponding loadings (B) and XPS compositions (C) for ester ClSi films soaked in 60/40 H2O/MeOH for up to 72 h. Variability of the ClSi film chemical composition increases with soak time, though it was determined that this was due to adsorption of an adventitious carbon contamination layer.
