Fund Project: We thank Mr. Hou Bu Li (National Key Laboratory of Thermostructure Composite Materials, Northwestern Polytechnical University) for the TG measurement. The project was supported by the Natural Science Foundation of Fujian Province of China (No. E0510002) and the National Natural Science Foundation of China (No. 50472056).

A highly branched polycarbosilane bearing allyl groups has been prepared by a one-pot synthesis with chloromethyltrichlorosilane, chloromethylmethyldichlorosilane and allyl chloride as the starting materials.The resultant polymer, with the approximate formula[SiH_1.2(CH₃)_0.71(CH₂CH=CH₂)_0.09CH₂]_n, has been characterized by ¹H, ¹³C, and ²⁹Si NMR, GPC, TG and elemental analysis.It could be cross-linked thermally at 170℃ in the absence of oxygen.Pyrolysis of the polymer gave a ceramic with a yield of about 70%.
