FTIR spectra of silicas with attached PMPS (samples 1–6) using different modification protocols and scheme (Table 1). The illustrations show the IR spectra of composites obtained by protocol 1 (samples 1–3, vol% of the modifying mixture at each stage 25/35/40) and protocol 2 (samples 4–6, vol% of the modifying mixture at each stage 40/35/25). The spectra for samples 2 and 5 are located according to the quantity of the modifying mixture at the first stage when the ratio of PMPS/DMC in the modifying mixture at different stages of modification was equal to 5.5
