  • Patent number: 10647840
    Abstract: A thermoplastic composition includes from about 50 wt. % to about 90 wt. % of a polymeric base resin and from about 10 wt. % to about 50 wt. % of a low dielectric constant (Dk)/low dissipation factor (Df) glass fiber component. The low Dk/low Df glass fiber component has a Dk of less than about 5.0 at a frequency of from 1 MHz to 1 GHz and a Df of less than about 0.002 at a frequency of from 1 MHz to 1 GHz. In certain aspects the thermoplastic composition has a Dk that is at least about 0.1 lower than a substantially identical reference composition that does not include the low Dk/low Df glass fiber component.

  • Publication number: 20190225799
    Abstract: The undesirable odor of poly(phenylene ether) has discouraged its adoption for some end uses. Melt-blending poly(phenylene ether) with a small amount of a phosphate salt or its hydrate is found to substantially reduce the odor without affecting physical or thermal properties. The odor-reduction method is applicable to poly(phenylene ether) alone or in combination with other resins.
