A polymer melt may be devolatilized to less than 500, preferably less than 150 ppm of residual volatile material by injecting into the melt an amount of a super critical fluid greater than the amount of residual volatile material in the melt, typically not more than about 10 weight %, and passing the melt through a flash chamber devolatilizer at a pressure of 12 mm of Hg or less at a temperature of from 200.degree. to 350.degree. C.
