POLYMER-FILLER COUPLING ADDITIVES

摘要

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.
