Abstract
The specification discloses a polyphenylene oxide delivery system for use in preparing an A-B-A block copolymer adhesive formulation having an increased service temperature. The delivery system comprises a preblend of polyphenylene oxide (PPO) resin having a T.sub.g within the range of from about 150.degree. to about 210.degree. C. and a B-block compatible resin. The PPO/B-block resin preblend enables introduction of more PPO into the composition thereby increasing the service temperature of the adhesive formulation.
