摘要： Disclosed herein are compositions comprising: from about 35 wt. % to about 85 wt. % of a polyphenylene ether component; from about 1 wt. % to about 55 wt. % of a polystyrene component; and from about 5 wt. % to about 25 wt. % of a flame retardant agent comprising an aromatic phosphoric ester, wherein the combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition. The composition may exhibit at least a VI flame rating at 1.5 mm measured according to UL 94 (2021) and a dissipation factor less than 0.002 when tested using a split post dielectric resonator and network analyzer.
