Abstract
The present invention discloses a novel polymer alloy that may be used as a casing for alkaline storage batteries. The present invention discloses a sealed alkaline storage battery comprising a cell in which power generating elements and an alkaline electrolyte are accommodated in a battery casing of a synthetic resin. The polymer alloy comprises polyphenylene ether, polystyrene and glass fibers. The polymer alloy of the present invention comprises about 30 to 45 weight % polyphenylene ether, about 30 to 45 weight % polystyrene and about 10 to 40 weight % glass fibers. Preferably, the polymer alloy comprises 1 to 1 ratio of polyphenylene ether to polystyrene and the polystyrene is high impact polystyrene. Additionally, the polymer alloy may further include 0 to 15 weight % of an elastomer.
