Hexaphenylcyclotrisilane polymerization during plastic flow under high pressure

The phenomenon of hexaphenylcyclotrisilane polymerization during plastic fl ow under high pressure was observed for the first time. Dependence of the d egree of monomer conversion on the deformation and pressure was established . The effect of various inert additives modifying the mechanical and electr ophysical parameters of the deformed system was studied. Application of a m agnetic field terminates the process of the hexaphenylcyclotrisilane polyme rization, in contrast to the case of acrylamide polymerization proceeding b y the free-radical mechanism insensitive to the external field.
