    摘要： Disclosed herein are non-dusting poly(phenylene ether) particles comprising 80 to 96 weight percent of poly(phenylene ether) particles having a mean particle size of 1 to 40 micrometers; and 4 to 20 weight percent of a liquid reactive diluent. Poly(alkenyl aromatic) resins, rubber-modified poly(alkenyl aromatic) resins, and hydrogenated, partially hydrogenated, and non-hydrogenated block copolymers of an alkenyl aromatic monomer and a conjugated diene are all excluded from the particles. The liquid reactive diluent is selected from a first polyol having at least two hydroxyl groups per molecule, a first epoxy resin, a first ethylenically unsaturated monomer, a polyether-modified polysiloxane, and combinations thereof. Also disclosed are compositions comprising the non-dusting poly(phenylene ether) particles and a thermoset composition, wherein the liquid reactive diluent is reactive with the components of the thermoset composition.
