✦ Synopsis

The polycarbosilanes (PCS) with meta-linkage bending unit ( -MezSim -CsH4 -Me& -CH2CH2 -) were successfully synthesized in mild conditions by hydrosilylation in the presence of [Pt{ (CHz=CHSiMe2)z0}2]. The PCS obtained were soluble in various solvents owing to the lowering of the crystallinity. These properties are well compared with those of the PCS [ -MezSi -p -C6H4 -MezSi -CHzCHz -1".
