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

An elastomeric composition is provided comprising at least one elastomer, at least one cellulose ester additive, at least one methylene acceptor, at least one methylene donor, and optionally, at least one filler; wherein the cellulose ester additive comprises at least one cellulose ester. The cellulose ester additive can also comprise at least one compatibilizer and/or plasticizer.

Elastomeric compositions comprising cellulose ester additives

A process for producing elastomeric composition is provided comprising mixing at least one elastomer, at least one cellulose ester additive, at least one methylene acceptor, at least one methylene donor, and optionally, at least one filler; wherein the cellulose ester additive comprises at least one cellulose ester. The cellulose ester additive can also comprise at least one compatibilizer and/or plasticizer.

Process to produce elastomeric compositions comprising cellulose ester additives

Branched polymers including multi-branched polymers, functionalized branched polymers, star-branched polymers, and dendigraft polymers. Methods for the synthesis of branched polymers and method for the use of branched polymers in tire components are also included.
