ABSTRACT:
A phenylene oxide polymer composition comprising (1) a phenylene oxide polymer; (2) a styrene/ethylene butylene/styrene block copolymer; and (3) a hydrated metal oxide; wherein the ratio by weight of the phenylene oxide polymer to the styrene/ethylene butylene/styrene block copolymer ranges from 90:10 to 10:90 and the content of the hydrated metal oxide ranges from 50 to 300 parts by weight per 100 parts by weight of the total amount of the phenylene oxide polymer and styrene/ethylene butylene/styrene block copolymer. This composition shows a high fire retardancy and little fuming and is excellent in tensile strength, elongation, low-temperature brittleness and organic solvent resistance.
