Abstract

Abstract Compound of the formula: WHEREIN R1 and R7 are each organic radicals of not more than 18 carbon atoms selected from the group consisting of hydrogen, hydrocarbyl, halohydrocarbyl and cyanoalkyl, R and R2 are each organic radicals of not more than 18 carbon atoms selected from the group consisting of hydrocarbyl, halohydrocarbyl, nitrohydrocarbyl and alkoxyhydrocarbyl, R3 is an organic radical of not more than 18 carbon atoms selected from the group consisting of hydrogen, hydrocarbyl, halohydrocarbyl, nitrohydrocarbyl, alkoxyhydrocarbyl, dialkylamino and WHEREIN R4 is an organic radical selected from the group consisting of aliphatic hydrocarbyl, aliphatic halohydrocarbyl, aliphatic nitrohydrocarbyl, and WHEREIN R5 and R6 are each aliphatic hydrocarbyl, a is an integer of 1 to 4, inclusive, b is an integer of 0 to 3, inclusive, d and e are each integers of 0 to 1, and the sum of a, b, d and e is 4. The imidatosilanes are useful as chain extenders and as curing agents in one-package RTV compositions.
