Abstract

Nonaqueous compositions comprising at least one product of the reaction betweenA) a linking agent of formula IR4(Y)3  (I)Wherein each Y group is a halogen atom or one Y group is a halogen atom and two Y groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R4 group to form an epoxy group, and R4 is an alkanetriyl group containing from 3 to 10 carbon atoms; andB) a compound of formula IIR3(EO)n(PO)m(BO)pX  (II)Wherein R3 is substituted or unsubstituted, saturated or unsaturated, organic oxy or thio group having from 1 to 36 carbon atoms or a primary or secondary amino group having from 1 to 36 carbon atoms; n is a number of from 0 to 50; m is a number of from 0 to 50; p is a number of from 0 to 50; and X is hydrogen, or X can be a mercapto group, an amino group, or a C1-C6 alkylamino group in place of a terminal —OH group, provided that when X is mercapto, amino or a C1-C6 alkylamino, the sum of n, m, and p must be at least 1; and the mole ratio of I:II is from about 0.1:1 to about 5:1.
