[0284] Example 1: Functionalization of silane resins by modification of polar linkers

[0285] In the following examples, various resins were functionalized with silane moieties, as described below. Functionalized resins can be synthesized using the different methods provided below, as well as other methods that will be apparent to those skilled in the art after reading the methods provided below. All chemicals were from Sigma-Aldrich (St. Louis, MO, USA) unless otherwise noted.

[0286] Example 1.1 - Synthesis of pendant silane-containing resins by acetoxystyrene functionalization

[0287] Steps 1A to 1C illustrate the synthesis of pendant silane-containing resins by functionalization of acetoxystyrene. Specifically, Scheme 1 shows an example of an ether route for the deprotection of acetoxystyrene-based resins to phenols, followed by ether formation, and silane formation at internal pendant group positions within the resin. functionalized. Note that in Schemes 1 to 5 below where the variables "r" and "q" appear, the representation on the left is of the functionalized moiety, not the entire resin backbone. In other words, the starting materials presented in these schemes represent many points of derivatization of the resin backbone, which is not represented or drawn in the scheme itself, but is implied. Derivatization occurs randomly throughout the resin backbone. The starting material representations do not indicate block copolymers or the use of b...

Abstract

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.
