Diagram of a comparison of morphological parameters of the modified silica samples. The diagram shows the specific surface area (BJH and t-plot), pore size, and pore volume of samples synthesized by protocol 1 (samples 1–3, vol.% of the modifying mixture at the each stage 25/35/40) and protocol 2 (samples 4–6, vol.% of the modifying mixture at the each stage 40/35/25) that are located according to the scheme “from long to short” (L-S): the ratio of PMPS/DMC in the modifying mixture at the different stages of modification was 20/5.8/3.4, respectively (at the first modifying step the long-chain oligomers are introduced to the reactor)
