Abstract: There is disclosed a process for preparing organic nano-particles comprising the steps of: (a) preparing a solution comprising an unsaturated polyester and/or a vinyl ester resin and a hydrophobic monomer; (b) dispersing the solution obtained in step (a) in an aqueous phase to form a stable emulsion where the aqueous phase is the continuous phase; and (c) using an initiator to cure the emulsion obtained in step (b) in the presence of a water soluble inhibitor to form a dispersion of nano-particles. The invention further provides organic nano-particles obtainable by the process according to the invention; various uses of said nano-particles; such as in paper, dye, toner and personal care compositions and topical medicaments comprising said nano-particles.

Abstract: Thermoset compositions and methods for forming three-dimensional articles via an additive fabrication process, and articles made therefrom are disclosed herein. In an embodiment, a composition comprises a first network-forming component comprising a TPA-based polyester comprising a backbone and having at least 2 polymerizable groups, one or more first network monomers, and a first network initiator. The backbone of the TPA-based polyester comprises the reaction product of a terephthalic acid and a polyol. The composition may further comprise a second network-forming component.
