Abstract:

Functionalization of matrix polymer is an attractive approach for improving the dispersity of carbon black (CB) especially in rubber-based composites, i.e., to introduce functional groups such as epoxy and carboxyl groups directly into rubber backbone to interact with the functional groups present on the CB surface. Better compatibil-ity between CB and rubber matrix could be achieved only upon application of high temperature molding or high temperature extrusion in the presence of silane coupling agent. However, few studies have been focused on the functionalization of matrix rubber by introducing multiple dimethylamino groups along the rubber backbone. These rubber-based composites containing finely dispersed CB could be applied particularly to tire tread rubber of green tire from the standpoint of running safety and fuel consumption. The number of dimethylamino groups along the random butadiene-styrene copolymer backbone is definitely controlled by the monomer feed ratio and polymer molecular weight. SEM observations revealed great improvement in terms of CB dispersion in such dimethylamino in-chain multi-functionalized rubber matrix. This provides an effective route to prepare rub-ber-based composites with good CB dispersion, which have potential applications in rubber reinforcement, bi-tumen binders, CB-filled elastomers and high-performance automotive tires and other advanced materials.
