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: The invention relates to fluoropolymers that have been modified with low molecular weight, polymeric chain transfer agents, and uses of the modified fluoropolymers. The modified fluoropolymers provide enhanced properties to the fluoropolymer, such as increased adhesion, and hydrophilic characteristics. The modified functional fluoropolymers are useful in many applications, including as binders in electrode-forming compositions and separator compositions, for hydrophilic membranes and hollow fiber membranes, as an aqueous and a solvent cast coating for baked decorative and protective coatings, and as a tie layer between a fluoropolymer layer and an incompatible polymer layer.
