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.

Abstract: Provided is a PSA sheet that shows excellent adhesive strength to both high-polar and low-polar adherends with reduced dependence on fossil-resource-based materials. The PSA sheet has a PSA layer formed from a natural rubber-based PSA. At least 20% by weight of all repeat units forming the base polymer of the PSA are derived from an acrylic monomer. Biomass-derived carbons account for at least 50% of the total carbon content of the PSA layer. The PSA sheet has an adhesive strength of 18 N/20 mm or greater to a stainless steel plate (after left at 50° C. for 2 h) and an adhesive strength of 15 N/20 mm or greater to a polypropylene plate (after left at 50° C. for 2 h).
