To increase the connectivity of the molecular structure but not to prevent softening, small amounts of tetraethoxysilane (TEOS) were added to phenyl‐substituted melting gels. The limit of the additions was determined when the melting gel lost its ability to soften. A comparison was made between TEOS diluted with ethanol, TEOS diluted with methanol, and tetramethoxysilane (TMOS) diluted with methanol. The additions had slight effects on the glass transition behavior, the gelling time and the indentation hardness. The role of the TEOS was both a form of dilution and a cross‐linking promoter.

四乙氧基硅烷（TEOS）对熔融凝胶行为的影响

为了增加分子结构的连通性但不防止软化，向苯基取代的熔融凝胶中添加了少量的四乙氧基硅烷（TEOS）。当熔融凝胶丧失其软化能力时确定添加的极限。比较了用乙醇稀释的TEOS，用甲醇稀释的TEOS和用甲醇稀释的四甲氧基硅烷（TMOS）。这些添加物对玻璃化转变行为，胶凝时间和压痕硬度影响很小。TEOS的作用既是稀释形式，又是交联促进剂。
