采用色谱质谱联用技术研究了1种复合醇盐：30％二甲基二乙氧基硅烷／70％正硅酸乙酯（DDS／TEOS）的水解聚合过程，并由此分析了这两种有机-无机酸盐的相互作用机制和聚合方式，实验结果指出，DDS的添加抑制了TEOS的自聚合，使得体系中形成了大量的DDS的自聚合环状分子（（（CH3）2Si—O—）n）以及TEOS和DDS的共聚合高分子，由于后者对水解聚合的加速作用，使得30％DDS／70％TEOS系统具有最短的凝胶时间。
A kind of complex alkoxide: 30% dimethyldiethoxysilane / 70% ethyl orthosilicate (DDS / TEOS) was studied by chromatographic and mass spectrometry Organic-inorganic acid salt interaction mechanism and polymerization mode, the experimental results show that the addition of DDS inhibits the TEOS self-polymerization, making the system formed a large number of DDS self-polymerization cyclic molecules (((CH3) 2Si-O- ) N), as well as the copolymerized polymer of TEOS and DDS, gave the shortest gel time for the 30% DDS / 70% TEOS system because of the accelerated effect of the latter on hydrolytic polymerization.
