Alkanedioxy titanium chelates

Abstract

Abstract Alkanedioxy titanium chelates have the formula: WHEREIN R2 is a radical selected from the group consisting of hydrogen, hydrocarbyl having not more than about 8 carbon atoms, carboxyalkyl and halohydrocarbyl having not more than about 8 carbon atoms and the total number of carbon atoms in the R2 and R6 substituted alkanedioxy radical is not more than about 18, R3 is a radical having not more than about 8 carbon atoms selected from the group consisting of hydrocarbyl, halohydrocarbyl and cyano lower alkyl, R6 can be selected from the same group as R2 and in addition can be halo, cyano, nitro, carboxy ester, acyl and hydrocarbly substituted by halo, cyano, nitro, carboxy ester and acyl, R7 is selected from the group consisting of hydrogen, hydrocarbyl, halohydrocarbyl, acyl, and taken together with R3 can form together with the carbon atoms to which they are attached cyclichydrocarbon substituents and chloro, nitro, acyl, cyano and carboxy ester substituted cyclic hydrocarbon substituents; X is a radical selected from the group consisting of hydrocarbyl, halohydrocarbyl, cyanoalkyl, alkoxy, haloalkoxy, cyanoalkoxy and amino, and n has a value of 0 to 8, and when X is methyl the alkanedioxy substituent is other than an ethanedioxy or a 2,2-dimethyl-1,3-propanedioxy substituent. When mixed with methyltrimethoxysilane and a silanol chainstopped polydiorganosiloxane fluid, these chelates catalyze the cure of the composition to a rubbery solid elastic state when exposed to atmospheric moisture.
