Synthesis of Polycarbosilane for SiC Precursor (II)
Polycarbosilane was synthesized from polydimethylsilane at 42$0^{circ}C$, pyrolysis temperature with various times And IR, NMR, UV, and GPC were detected. Average molecular weight Mn was increased proportionally with the reaction time. Average molecular weight of polycarbosilane was about 700(n=20), which has chain structure and the product yield was 72%.
