Ammunition boxes may be equipped with a cohesive and adhesive shell restraining overlay adapted to restrain ammunition shells in a stabilized position. The shell restraining overlay provides sufficient adhesiveness to restrain a housed ammunition shell at a desired shell position, but allows for relatively effortless shell release without creating excessive movement or noise. The stabilizing overlay also stabilizes the shells from inadvertent spillage from the ammunition box.

A unique flexible container combination comprises a viscoelastomeric thermoset overlay disposed upon a flexible supportive base. Desirably, the viscoelastomeric thermoset overlay possesses exceptional adhesive, cohesive and releasability properties. In some embodiments, the flexible container combination can also exhibit antipathogenic, cleansability and/or reusability properties. The flexible container combination can maintain an adhered stowable item in an immobilized position until intentionally removed therefrom by a user. In some embodiments, the flexible container combination can be folded or rolled into a rolled-up configuration.

A method for making a plasticized polymer comprises polymerizing a polymerizable monomer, such as an ethylenically unsaturated monomer, in a plasticizer, such as mineral oil, and in the presence of a catalyst system. The plasticized polymer may be mixed with a tackifying resin in a method for making an adhesive. A composition, which may be useful as an adhesive, comprises a polymer system comprising a first polymer; a plasticized system comprising a first plasticizer that was in the presence of the first polymer during the polymerization step to make the first polymer; and a tackifier. The method can be used to make compositions having polymers with a low density or a low molecular weight or both. The final compositions made by methods of the invention include adhesives, sealants, coating, or lubricants.

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 present invention provides floor mats possessing antipathogenic, cohesive, viscoelastomeric and adhesive attributes for removing foot and/or sole borne contaminants. A thermoset reaction product derived from a reaction media of a carefully balanced ratio of isocyanate prepolymer, polyether diols and triols, and organic plasticizers effectively provides a floor mat overlay for adhesively retaining and preventing the spreading of foot or sole borne pathogens and other contaminants.

An adhesive composition contains a -1,3-glucan derivative obtained by introducing an acyl group into -1,3-glucan; and a petroleum-based resin. An adhesive tape includes an adhesive layer formed from the adhesive composition.
