Аннотация:A number of polycarbosilanes (PCS) with various types of terminal groups were synthesized by the Grignard reaction with (chloroalkyl)alkoxysilanes. Their structure and properties were studied by NMR, IR spectroscopy, GPC, and TGA method. The dependence of the coke residue formation on the structure of the polymer and the nature of its terminal groups has been estimated. It was demonstrated that PCS based on (chloroalkyl)trialkoxysilanes with terminal ethynyl groups are perspective precursors for SiC ceramics fabrication.
