Abstract: A reinforced composition includes particular amounts of a compatibilized blend including a polyamide, a polyphenylene ether, a functionalizing agent in an amount sufficient to effect compatibilization, and optionally, a high impact polystyrene, wherein a weight ratio of the polyamide to the polyphenylene ether and the high impact polystyrene is 1:2 to 3:1. The reinforced composition further includes of glass fibers having a dielectric constant of less than 5.0 at a frequency of 1 MHz to 1 GHz and a dissipation factor of less than 0.002 at a frequency of 1 MHz to 1 GHz. The composition has a dielectric constant of less than 4 at a frequency of 1 MHz to 5 GHz and a dissipation factor of less than 0.012 at a frequency of 1 MHz to 5 GHz.

Abstract: A reinforced poly(phthalamide) composition comprising 20-80 weight percent of a poly(phthalamide) component comprising 15-55 weight percent of a crystalline poly(phthalamide), and 5-45 weight percent of an amorphous poly(phthalamide); 0.5-60 weight percent of a reinforcing filler; and 0.1-50 weight percent of an additive composition; wherein weight percent is based on the total weight of the reinforced poly(phthalamide) composition and totals 100; and wherein the reinforced poly(phthalamide) composition has a capillary melt viscosity, measured according to ASTM D3835 (2015) at 320° C., at 5000 s−1, that is at least 10% lower than that of the same reinforced poly(phthalamide) composition without the amorphous poly(phthalamide), and a warpage that is at least 15% lower than that of the same reinforced poly(phthalamide) composition without the amorphous poly(phthalamide).
