Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.

Described herein are hydrocarbon polymer modifiers for use in various applications. The hydrocarbon polymer modifier comprises a cyclic component, and has a glass transition temperature and Mn defined by the following two equations: (1) Tg952.2*(% H Ar), and (2) Tg53+(0.265*Mn); an aromatic proton content (% H Ar) of from 12 mole % to 19 mole %; and an Mn of from 300 g/mole to 450 g/mole, wherein Tg is glass transition temperature as expressed in C. of the modifier, the % H Ar represents the content of aromatic protons in the hydrocarbon polymer modifier, Mn represents the number average molecular weight of the hydrocarbon polymer modifier, and the cyclic component is selected from the group of a distillation cut from a petroleum refinery stream, and/or C.sub.4, C.sub.5 or C.sub.6 cyclic olefins and mixtures thereof. Further, the hydrocarbon polymer modifier may be characterized by a Tg of from 70 C. to 95 C. and/or a z-average molecular weight (Mz) of the hydrocarbon polymer modifier of less than 1000 g/mole. The hydrocarbon modifiers are particularly useful in high Tg applications where low molecular weight resin is desirable.
