    Abstract: Novel compounds of the general formula: ##STR1## wherein: (a) each R.sup.1 is a hydrocarbyl group, or a group of the formula: ##STR2## and each R.sup.1 may be the same as, or different from, any other group R.sup.1.(b) R.sup.2 is a group as defined for R.sup.1, or a group of the formula:--O(R.sup.5 O).sub.n Si(R.sup.1).sub.3 (iv) and each group R.sup.2 may be the same as, or different from, any other group R.sup.2.(c) each of R.sup.3 and R.sup.4 is independently a group of the formula: ##STR3##--(R.sup.5 O).sub.n --R.sup.6 (vii)(d) R.sup.5 is an alkylene or an arylene group and each R.sup.5 may be the same as, or different from, any other group R.sup.5,(e) R.sup.6 is a hydrocarbyl group of hydrogen and each group R.sup.6 may be the same as, or different from, any other group R.sup.6,(f) n is zero or an integer and each n may be the same as, or different from, any other n.The compounds are useful as water scavengers, particularly for hydraulic fluids, as well as in paints, lubricating oils and electrical oils.
