Reactive processing of silica-reinforced tire rubber : new
The silane chemistry during rubber processing is very complicated. Basically, from a processing point of view, two coupling reactions take place via TESPT. The first reaction is a coupling reaction between the TESPT molecule and the silica surface, the so-called silanization reaction. For this reaction hydrolysis of TESPT is required.

SILICA-REINFORCED NATURAL RUBBER TIRE TREAD COMPOUNDS
The feasibility of the use of epoxidized palm oil (EPO) and amine-modified epoxidized palm oil (mEPO) as process oils in silica-reinforced natural rubber compounds is studied. The chemical structures of EPO and mEPO are characterized by Fourier transform infrared spectroscopy and proton nuclear magnetic resonance spectroscopy (1 H-NMR). Amine modification for 3 and 5 h leads to mEPOs with 0.03 and 0.04 mmol of amine in 1 g of oil, referred to as 0.03 mEPO and 0.04 mEPO, respectively.

Silica-reinforced tire tread compounds compatibilized by
ENR is used as “green” compatibilizer for silica-reinforced rubber. Interactions between the epoxide and silanol groups enhance compatibilization. Filler–filler interactions can be effectively suppressed by the epoxide groups.

The development of sulphur-functional silanes as coupling
the history of sulphur-based rubber silane development on the basis of this silane. The silica-reactive unit (a) is generally a trialkoxysilyl group, of which the rate of reaction is controlled primarily by the alkoxy substituents. As a rule of thumb, the reactivity decreases as the length of the alcohol increases [2].
