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.

A method of forming a photo-cured layer on a substrate can include applying a first photocurable composition overlying a first region of the substrate and a second photocurable composition overlying a second region of the substrate and photo-curing the applied compositions, wherein the first region is a center region of the substrate and the second region is an edge region of the substrate, and the second photocurable composition has a higher vapor pressure than the first photocurable composition. The method can have the advantage that the forming of an extrusion within the edge region of the photo-cured layer can be avoided or being kept very low.
