“…The 1 H and 13 C chemical shifts were measured in relation to the signal of the solvent CDCl 3 . The 29 Si chemical shifts were measured in relation to TMS used as the external standard. The 11 B{H} chemical shifts were measured in relation to BF 3 •(C 2 H 5 ) 2 O used as the external standard.…”

“…One of the innovative approaches to the preparation of elastomer compositions involves the creation of so-called "molecular composites". [23][24][25][26][27][28][29][30][31][32][33][34] Composites of this type have a number of advantages compared to the traditional composite materials owing to the specifics of the preparation of such systems, namely mixing a polymer matrix and a nanoscale molecular filler. The possibility of modifying the chemical structure of fillers along with their dimensions and concentration makes it possible to vary the characteristics of the composites in a controlled manner.…”
