MODIFIED RESINS AND USES THEREOF

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.

Stabilized storage containers

The invention provides a unique container combination comprised of a container equipped with a thermoset viscoelastomeric interfacing section which serves to confine items placed thereupon. The interfacing viscoelastomeric section may be chemically bonded to the container support or cohesively bonded thereto. The interfacing thermoset viscoelastomeric section adhesively immobilizes items placed thereupon while tenaciously clinging (chemically or adhesively) to the container supportive structure. Containers equipped with the thermoset viscoelastomeric section surprisingly create an aseptic environment especially adaptable to hygienic applications while also affording superior protection against impact damage.
