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.

Functionalized resin having a polar linker

Modified thermoplastic hydrocarbon thermoplastic resins are provided, as well as methods of their manufacture and uses thereof in rubber compositions. The modified thermoplastic resins are modified by decreasing the relative quantity of the dimer, trimer, tetramer, and pentamer oligomers as compared to the corresponding unmodified thermoplastic resin polymers, resulting in a product that exhibits a greater shift in the glass transition temperature of the elastomer(s) used in tire formulations. This translates to better viscoelastic predictors of tire tread performance, such as wet grip and rolling resistance. The modified thermoplastic resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the modified thermoplastic resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, snow performance, and wet braking performance.

Modified resins and uses thereof

Disclosed are sulfur-crosslinkable rubber mixtures for the base of treads having a cap/base construction of vehicle tires, and a vehicle tire comprising the sulfur-crosslinkable rubber mixtures. The disclosed rubber mixture comprises: at least one diene rubber, 15 to 55 phr of at least one filler, at least one hydrocarbon resin comprising 25% to 100% by weight of aromatic monomers, having a softening point according to ASTM E 28 (ring and ball) of 70&#xb0; C. to 130&#xb0; C., and 0 phr of further plasticizers, that is, the sulfur-crosslinkable rubber mixture is free from further plasticizers.

Rubber mixture and vehicle tires

A sulfur-crosslinkable rubber mixture includes from 40 to 100 phr of at least one natural and/or synthetic polyisoprene, and 15 phr or more of at least one hydrocarbon resin which is built up to the extent of 50 to 100 wt. % from aliphatic Cmonomers and to the extent of 0 to 50 wt. % from further monomers, where the hydrocarbon resin according to formula I) has a Q of from 0.015 [&#xb0; C.&#xb7;mol/g] to 0.050 [&#xb0; C.&#xb7;mol/g]. Formula I) is defined as Q=softening point [&#xb0; C.]/centrifuge average Mc [g/mol]. In some aspects, the sulfur-crosslinkable rubber mixture includes 15 to 300 phr of the hydrocarbon resin, or even from 36 to 100 phr of the hydrocarbon resin. The further monomer(s) is or are selected from the group of unsaturated compounds, which can be polymerized cationically, which includes aromatics and/or unsaturated terpenes and/or alkenes and/or cycloalkenes.
