In some embodiments, a pressure vessel comprises a rounded container comprising a thermoplastic composition. The thermoplastic composition comprises a siloxane copolymer having a structural unit of the formula (11) where x and y are integers representing the number of repeating units; and x is at least 1. The pressure vessel is configured to receive a fluid at an operating pressure of greater than or equal to 2 bar.

Articles prepared from thermoplastic compositions, and method of preparing such articles

A composition useful for the injection molding of fluid engineering parts includes specific amounts of a high molecular weight poly(phenylene ether), a polystyrene, and glass fibers. The composition provides improved hydrostability and reduces or eliminates the butadiene monomer that is present in comparative compositions containing rubber-modified polystyrene. Fluid engineering articles prepared from the composition are described.
