Abstract: Embodiments of organic peroxide formulations provide longer scorch time protection and require fewer additives. The peroxide formulations may include, for example, at least one organic peroxide, at least one nitroxide-containing compound (e.g., 4-hydroxy-TEMPO), and at least one quinone-containing compound (e.g., mono-tert-butylhydroquinone).

Abstract: A container which is useful for safely storing and transporting compositions, such as liquid organic peroxide-containing compositions, which may be flammable, combustible, susceptible to exothermic decomposition, explosive and/or otherwise hazardous, is provided. The container includes a containment vessel having thermoset polymer-containing walls, as well as a vent mechanism. The containment vessel may be manufactured by a rotational molding process using a thermoplastic polymer, such as a polyethylene, which is crosslinked to provide the thermoset polymer.

Abstract: Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).

Abstract: An organic peroxide composition is provided which is liquid or near liquid at 25° C. or a low melting solid and which includes at least one ethylenically unsaturated organic peroxide (i.e., an organic peroxide containing at least one carbon-carbon double bond) and at least one saturated organic peroxide. The organic peroxide composition may further include at least one mono- and/or poly-unsaturated compound and at least one free-radical trap. The organic peroxide can be blended into a polymer such as a powdered or granular polyethylene resin. This peroxide-containing polymer can be used in rotational molding, wherein the polymer is added to a mold which is heated in an oven with rotation, thereby melting the polymer and coating the inside of the mold.

Abstract: An organic peroxide formulation includes at least one organic peroxide and at least one cellulose compound. Embodiments of the organic peroxide formulations significant improvements in surface tackiness (often including but not limited to tack-free surfaces) when curing elastomers in the presence of oxygen. Embodiments of the present invention relate to organic peroxide formulations that can cure solid elastomers in the full or partial presence of oxygen using, for example, a hot air oven or tunnel, molten salt bath, or steam autoclave. Embodiments of the invention also relate to crosslinkable elastomer compositions, processes for curing the elastomers, and products made by such processes.
