摘要：

The hydrolysis of the linear siloxanes SinOn_1(OCH3)(2n+2) (n=1-3), the monomeric silylated silanes [(H3C)(3)SiO]Si-n(OCH3)(4_n) (n = 1-3) and the cyclic species SInOn(OCH3)(2n)(n = 3, 4) was studied by Si-29 NMR in the absence of a catalyst. The regions of chemical shifts of their partial hydrolyzed building units were determined as well as the rate constants of the single hydrolysis steps on the level of their building units.
