Participants

Reaction Steps

A polymer solution of about 41.9% polyphenylene ether, 38.0% polystyrene, 3.9% polybutadiene rubber, 2.6% styrene and 13.6% toluene solvent was delivered at a rate of 59.6 pounds/hour at an initial temperature of 198° C. The vessel was maintained at about 400 Torr during the run. About 9.6 pounds/hour of styrene/toluene were vaporized leaving a foaming product of about 50 lbs/hour to settle at the bottom of the vessel for recovery.
