14.8 Conclusions
The Si-H bond is much more reactive than the C-H bond. Thus, polysiloxanes containing Si-H functionality are a very important group of silicones. They are most
frequently applied as crosslinking agents (not only for silicone elastomers and rubbers) and reducing agents, superhydrophobic coating materials and reagents useful
for modifying different polymers and polymeric materials, often via hydrosilylation
reactions. Other hydrosilyl functional organosilicon polymers and especially polysilanes, polycarbosilanes and polysilazanes also find many practical applications,
e.g. as preceramic and photoresist materials.
Acknowledgments Author is very grateful to Management Staff of ŁUKASIEWICZ Research
Network - Textile Research Institute in Łódź (Poland) for possibility to prepare the manuscript of
this Chapter, a financial support, and encouraging, enthusiastic atmosphere at workplace. This
Chapter is dedicated to a memory of my excellent teachers and outstanding, world-famous organosilicon chemists: Prof. Zygmunt Lasocki (1921-1993) who had worked at the Lodz University of
Technology in Łódź (Poland) and Prof. Adrian G. Brook (1924-2013) who had worked at the
University of Toronto (Ontario, Canada).
Conflicts of Interest The author declares no conflict of interest.
