摘要

A new method for the production of foamed thermoplastic polymers from blends of a poly(aryl ether ketone) (PAEK) and polyetherimide (PEI) is presented. The blowing agent for the foaming process is water which is produced at elevated temperatures in an extruder, via an in situ reaction between an amine end group on the PEI, and a ketone functionality on the backbone of the PAEK chain. The effect of composition, mixing, time, and temperature are investigated. (C) 1997 John Wiley & Sons, Inc. [References: 49]
