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.

Abstract: A coupling agent formulation for cellulosic material-polymer composites is provided. The formulation includes a) at least one organic peroxide; and b) at least one of i) at least one zinc-containing reagent; and/or ii) at least one silicon-containing reagent. The coupling agent formulations produce polymer matrix cellulosic material composites with improved strength and aging characteristics. The improved strength may be related to physical properties such as improved stiffness, toughness or tensile strength. A masterbatch utilizing the coupling agent formulation is provided, as well as a method making the masterbatch.

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: Formulations for producing modified bio-based polymers, especially bio-based polyesters like PLA and/or biodegradable polymers like PBAT, include at least one organic peroxide and at least one bio-based reactive additive. The at least one organic peroxide and/or the at least one bio-based reacted additive are capable of reacting with a bio-based polymer and/or biodegradable polymer to produce the modified bio-based and/or modified biodegradable polymer. The modified bio-based and/or modified biodegradable polymers have improved properties compared to non-modified bio-based and/or biodegradable polymers. The improved properties may related to processability, especially improved melt strength which results in easier processing while producing foamed polymers, thin films, such as blown film, cast film, tentered film and the like. The improved properties may be related to physical properties such as improved stiffness, toughness or tensile strength.

Abstract: The efficacy of peroxy compounds such as hydrogen peroxide in bleaching compositions and the like may be enhanced by the presence of manganese carboxylates containing branched chain carboxylate and/or tartrate groups. The invention relates to the activation of peroxy compounds using particular types of manganese carboxylates so as to render such compounds more effective in bleaching stains from substrate surfaces and other such applications.
