Disclosed are resin compositions that include poly(arylene ether), HIPS/GPPS), impact modifier, and ceramic filer that provide various Dk values while maintaining Df at a very low level. The compositions also possess excellent mechanical and processing performance, for example, superior high impact strength and good ductility, compared to prior art compositions. The compositions can be used to form components of wireless electronic communications devices in order to ensure a low degree of signal attenuation.

Four new compounds, spinulosin-hydrate (VI), spinulosin quinol-hydrate (II), dihydrospinulosin quinol (VII), and fumigatin chlorohydrin (VIII) were isolated from the culture medium of Aspergillus fumigatus DH 413 and Fersenius 4399 by ion exchange chromatography, and their chemical structures were determined. From the tracer experiments using 14C-labeled compounds, the metabolic relationships among metabolites were proposed as shown in Chart 4. The key different point between spinulosin producing and unproducing strains in Aspergillus fumigatus were also discussed.
