摘要：

利用硅氢加成反应，以4-乙烯基苯并环丁烯(4-VBCB)和1,1,3,3-四甲基-1,3-二氢二硅氧烷（TMHS）为原料，一步法合成了二乙基硅氧烷双苯并环丁烯（DES-bis-BCB），并对以其为单体在热引发条件下生成的预聚体进行了结构表征。 利用原子力显微镜和热重分析对预聚体的成膜性能和热性能进行了分析。 结果显示，薄膜的均方根（RMS）糙度为0.53 nm，初始分解温度为390 ℃，表明二乙基硅氧烷双苯并环丁烯聚合物具有良好的成膜性能和优异的热稳定性能。

关键词: 双苯并环丁烯, 硅氢加成反应, 热性能, 成膜性能。

Abstract:

Hydrosilylation reaction of 4-vinylbenzocyclobutene(4-VBCB) with 1,1,3,3-tetramethyl-1,3-dihydro-disiloxane(TMHS) was employed to afford the monomer of diethyl tetramethyl disiloxane-bisbenzocyclobutene(DES-bis-BCB). The structures of DES-bis-BCB and the prepolymer prepared from DES-bis-BCB by thermal isomerization ring opening polymerization reaction were characterized and analyzed. The surface morphology and thermal stability of the films were investigated by atomic force microscopy(AFM) and thermogravimetric analysis(TGA), respectively. The results showed that the root-mean square(RMS) roughness was 0.53 nm, and the starting mass loss temperature was about 390 ℃. It indicated that DES-bis-BCB exhibited good film-forming property and excellent thermal stability.

Key words: bisbenzocyclobutene, hydrosilylation reaction, thermal properties, film-forming property.
