Ionomeric polymer compositions are provided which comprise an ionomeric polymer and about 5 to about 125 parts by weight of gilsonite, per 100 parts by weight of the ionomeric polymer. The inventive compositions can be formulated as processable materials which can be fabricated into articles such as sheets, tubes, and films having improved tear propagation resistance and fire retardance and decreased levels of water absorption.
