ABSTRACT:
The molding defect known as “splay” is reduced in poly(arylene ether) injection molding compositions including specific amounts of poly(arylene ether), rubber-modified polystyrene, triaryl phosphate, and aryl phosphite. The molding compositions are particularly useful for injection molding articles with large, thin sections, such as battery cases for the back-up batteries used in wireless towers.
