Problems solved by technology

However, no poly(phenylene ether) specifically for micronization is known
Also, when particulate solids are used as additives in thermoplastic or thermoset compositions, any anti-dusting agent present remains a contaminant in the composition and can adversely affect the physical properties of the composition

Abstract

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.

Description

Background technique [0001] Poly(phenylene ether)s are a class of plastics known for their excellent water resistance, dimensional stability, dielectric properties, and inherent flame retardancy. Properties such as strength, stiffness, chemical resistance, and heat resistance can be tuned by blending poly(phenylene ether) with various other plastics and additives to meet the needs of a variety of consumer products such as sanitary ware , electrical boxes, automotive components and insulators for wires and cables. [0002] Micronized (micronized) poly(phenylene ether) can be used as an organic filler for some plastics. As mentioned in copending U.S. Patent Serial Nos. 13 / 538,295 and 13 / 657,829, micronized poly(phenylene ether) can reinforce epoxy resins and polyurethane and polyisocyanurate foams Toughness, heat resistance, dielectric properties, water resistance or flame retardancy. However, since micronized poly(phenylene ether) contains ultrafine particles, it can have hi...
