New thermally stable fluids and additives

Summary

• 1. Studies have been made of the thermal-oxidative stability of a series of 8-oxyquinolinetitaniumdimethylsiloxanes of the general formula (1) with varying degrees of polymerization. It has been shown that the gelling time in thermal-oxidative destruction depends on the concentration of 8-oxyquinolinetitanoxane groups and is at a maximum with a content of these groups of 0.18–0.30%, calculated as titanium.

• 2. It has been shown that 8-oxyquinolinetitaniumdimethylsiloxanes of both branched and linear structure are extremely effective inhibitors of the thermal-oxidative destruction of polydimethylsiloxanes.
