ABSTRACT:
A composition of matter is disclosed that comprises a compound of the formula AnR, wherein:A isR1is hydrocarbyl;m is 0 or 1;n is 1, 2, or 3;R is selected from the group consisting of:mono-, di-, and trivalent aliphatic groups; mono-, di-, and trivalent aromatic groups; five- and six-membered heterocyclic rings comprising n carbon atoms bonded to A, at least one nitrogen atom, and, optionally, at least one sulfur atom; andwherein R2and R3are independently selected from the group consisting of hydrogen and hydrocarbyl. These compounds are useful as coupling agents in filled elastomer compositions.
