Апстракт:
Siloxane equilibration reaction in the presence of appropriate functional disiloxanes is a common method for synthesis of telechelic siloxane oligomers. Due to high reaction temperature, synthesis of hydoxy-terminated polysiloxane are accompanied by number side reactions. In this paper, the synthesis of hydroxy-terminated siloxane oligomers at relatively low temperatures was optimized. The oligomers of the controlled molecular weight was synthesized in the presence of heterogeneous catalyst and characterized by spectroscopic and thermal methods, as well as thermogravimetric analysis - infrared spectroscopy (TG-FTIR) and dilute solution viscometry. Keywords: hydroxy-terminated PDMS, siloxane equilibration reaction, 1H NMR spectroscopy

Кључне речи:
hydroxy-terminated PDMS, siloxane equilibration reaction, 1H NMR spectroscopy
