Abstract
A thermoplastic composition includes particular amounts of poly(phenylene ether) having an intrinsic viscosity of greater than 0.5 to 1.45 deciliters per gram and a homopolystyrene. The composition can advantageously provide improved fatigue performance. The composition can be particularly useful for water-contacting articles.
Claims18
A thermoplastic composition comprising:
- 30 to 85 weight percent of a first poly(phenylene ether) having an intrinsic viscosity of greater than 0.5 to
- 1.45 deciliters per gram, measured at 25° C. in chloroform using an Ubbelohde viscometer, and
- optionally, a second poly(phenylene ether) having an intrinsic viscosity of 0.3 to 0.5 deciliters per gram, measured at 25° C. in chloroform using an Ubbelohde viscometer,
- provided that a weighted average of the intrinsic viscosity of the first poly(phenylene ether) and the second poly(phenylene ether) is greater than 0.5 deciliters per gram;
- and
- 15 to 70 weight percent of a homopolystyrene;
- wherein weight percent of each component is based on the total weight of the composition.
