Saccharide-containing conjugates as eco-friendly coupling agents for silica reinforced rubber compounds

Silica reinforced rubber is used as a tire tread compound due to its desirable viscoelastic properties. To achieve proper silica dispersion in rubber compound, silane-based coupling agents are required. In this study, we synthesize saccharide-containing molecules and investigate their uses as green...
