Effect of nano-sized titania (NST) prepared by sulfate technique (anatase and η-TiO2) and commercial Degussa P25 on properties of their composites with 1,2-polybutadiene (1,2PB) is studied by a complex of methods. Mixtures were prepared with LB 300 160/160 laboratory rolls by stirring for 10 min. Elastomer was first modified with a curative group (sulfur, zinc oxide, stearic acid, dibenzothiazolylsulfide and tetramethyltiuramdisulfide) and then with NST. The NST structure is shown to affect the degree of interaction between 1,2-PB and titania. Titania introduction extends the temperature range of the material working capacity.
