The dispersion of fillers such as carbon black, oxidized carbon black, silica, other mineral fillers, or mixtures thereof in polymeric compositions is improved by the use of a polymer-filler coupling compound, Q-A-B. In polymer-filler coupling compound Q-A-B, Q is a dipolar nitrogen-containing moiety that can form a 1,3 dipolar addition to an unsaturated carbon-carbon bond; B is an oxazoline, thiazoline, alkoxysilane or allyltin moiety, and A is a linking atom or group that forms a bridge between Q and B. |
