Steps in the processing of oils derived from plants or vegetables include the degumming, deodorizing and bleaching of the oil before it can be used for further applications. By eliminating one or more of these steps from the processing of the oil, followed by hydrogenating the oil to a specified degree of hydrogenation, the resulting upgraded oils can be incorporated into products having commercial applications. The process uses a high shear mixing device and a hydrogenation catalyst. The process can utilize a single or multiple high shear devices, and utilize renewable oils instead of increasingly scarce petroleum based products. The resulting hydrogenated products may then be utilized in a variety of other commercial applications, such as to render cellulosic products water resistant, provide a coating for numerous cellulosic products, adhesive compositions, ink compositions, firelog compositions, drilling muds or asphalt modifiers. 1.

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.

The adhesive layer comprises at least two different heat-activated adhesive materials in alternative sequences over the surface of the core structure, the heat-activated adhesive materials being activated at different temperatures. As the tapes are processed in the laminating machines, some of the adhesives will be heat activated with enough operating range that the tapes will have the proper adhesion to the substrate in any operating conditions, and some of the adhesives will set at the exit of the laminating machines also at any operating conditions of the laminating machines. Hence the tapes will have a much larger operating envelope under a very large range of operating conditions in the laminating machines.
