&amp;alpha;-Amine ketoximesilanes are proven to be effective crosslinkers in the preparation of ketone-oxime one-component room temperature vulcanized (RTV) silicone rubber without the use of toxic metal catalyst. This work aimed to investigate the hydrolysis kinetic of &amp;alpha;-amine ketoximesilanes, which is vitally important for the preparation of RTV silicone rubber. Five kinds of &amp;alpha;-amine ketoximesilanes, namely &amp;alpha;-(N,N-diethyl)aminomethyltri(methylethylketoxime)silane (DEMOS), &amp;alpha;-(N,N-di-n-butyl)aminomethyltri(methylethylketoxime)silane (DBMOS), &amp;alpha;-(N-n-butyl)aminomethyltri(methylethylketoxime)silane (n-BMOS), &amp;alpha;-(N-cyclohexyl)aminomethyltri(methylethylketoxime)silane (CMOS) and &amp;alpha;-(&amp;beta;-aminomethyl)aminomethyltri(methylethylketoxime)silane (AEMOS), were successfully obtained and confirmed using Fourier transform infrared spectrometer (FT-IR) and hydrogen-1 nuclear magnetic resonance ( ¹H NMR). Kinetics of hydrolysis reactions were measured by FT-IR and conductivity. Our results illustrated that the kinetic constant rates ranged from 12.2 &amp;times; 10 &amp;minus;4 s &amp;minus;1 to 7.6 &amp;times; 10 &amp;minus;4 s &amp;minus;1 , with the decreasing order of DEMOS &gt; n-BMOS &gt; DBMOS &gt; CMOS &gt; AEMOS at the given temperature and humidity. Better performances of thermal stability could be achieved when using the &amp;alpha;-amine ketoximesilanes as crosslinkers in the preparation of RTV silicon rubber than that of RTV silicone rubber with the use of methyltri(methylethylketoxime)silane (MOS) as a crosslinker and organic tin as a catalyst.
