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.

Abstract: The invention relates to 3D printed parts made with thermoplastic polymers having a low stiffening temperature. 3D printed parts of the invention have very good Z layer adhesion, have a high elongation at break in the Z direction, preferably of more than 50 percent, and have at least an 80 percent ratio of Z to XY stress at yield or at break. The resulting part may be nearly isotropic—having similar mechanical properties in the XY and Z print directions. The excellent layer adhesion makes the resultant printed part more robust—able to withstand many cycles of use. Certain polymers of the invention produce printed parts that have a very low haze, and are nearly transparent.
