| 摘要 |
Azasilacycloalkyl functional alkoxysilanes which are useful for making polymers for room temperature vulcanizable compositions and as adhesion promoters are exemplified by 1-(3-(2,2,4-trimethyl-1-aza-2-silacyclopentyl)propyl)-3-(2-trimethoxys ilylethyl)-1,1,3,3-tetramethyldisiloxane and 1-(2-(1,2,4-trimethyl-1-aza-2-silacyclopentyl)ethyl)-3-(2-trimethoxysi lylethyl)-1,1,3,3-tetramethyldisiloxane. The methoxy functional azasilacycloalkyl functional compounds can be made from disiloxanes having a silicon-bonded hydrogen atom such as 1-(3-(2,2,4-trimethyl-1-aza-silacyclopentyl)propyl-1,1,3,3-tetramethyl disiloxane. |
