以聚硼硅氮烷（PSNB）、N-乙烯基吡咯烷酮（NVP）为原料，由过氧化二异丙苯（DCP）引发自由基共聚合反应，制备了聚硼硅氮烷（PSNB/NVP）杂化树脂。采用差示扫描量热仪、热失重仪、红外光谱仪、平板流变仪等对杂化树脂的热性能、固化过程、流变行为等进行测试。结果表明，随着PSNB与NVP的质量比的提高，杂化树脂的热稳定性升高，PSNB与NVP质量比为20/80的杂化树脂在热质量损失率达到为5％时的温度较聚N-乙烯基吡咯烷酮提高近200℃；由杂化树脂高温裂解可得到硅硼碳氮多孔陶瓷，其孔尺寸及分布极不均匀。

A novel polyborosilazane (PSNB)and NVP hybrid resin was prepared by free radical copoly-merization of PSNB and 1-vinyl-2-pyrrolidinone with the initiation of dicumyl peroxide. The thermal proper-ties,curing behavior and rheological properties were characterized by DSC,TGA,FT IR and parallel plate rheometer. The thermal stability of the hybrid resin increased with increasing proportion of PSNB. The temper-ature of the 5% mass loss of the hybrid resin was increased about 200℃ with 20% weight percent of PSNB. SiBCN porous ceramics were prepared by pyrolysis of the hybrid resin under high temperature with the uneven pore size and distribution.
