POLYCARBOSILANE AND ITS MANUFACTURE

The Si units of the novel polycarbosilanes are linked by phenyl-substituted methylene bridges or by partially or fully fluorinated hydrocarbon bridges. The novel polycarbosilanes are obtained by a Grignard polycondensation reaction. Any phenyl substituents on the silicon atoms in the novel polycarbo...

Zusammenfassung:	The Si units of the novel polycarbosilanes are linked by phenyl-substituted methylene bridges or by partially or fully fluorinated hydrocarbon bridges. The novel polycarbosilanes are obtained by a Grignard polycondensation reaction. Any phenyl substituents on the silicon atoms in the novel polycarbosilanes may optionally also be replaced by halogen atoms by subsequent halogenation reactions, so that it is also possible to obtain polycarbosilanes which are both fluorinated in the hydrocarbon bridges and halogenated, in particular fluorinated, on the silicon atoms.
