Oligo (methylsilylene)-ethynylene polymer with erosslinkable ethynyl unit in the main chain was synthesized by condensation of α, ω-dicholorooligo (methylsilane) with dilithioacetylene. The as-synthesized polymer was characterized by GPC, FT-IR and NMR. The results showed ethynyl group was successfully introduced to the polymer main chain. The ceramic yield was dramatically increased by the cross-polymerization of ethynyl group, and the excess silicon of PMS was compensated. Nearstoichiometric (C/Si=1.17) and partial crystallization β-SiC monoliths were obtained by pressureless pyrolysing PSPA at 1200℃in a high yield (73.6 wt%).
