PROCESS FOR CONTINUOUSLY PRODUCINGɛ-CAPROLACTONE POLYMER

摘要

A process for the continuous production of an ϵ−caprolactone polymer which comprises heating an ϵ−caprolactone polymer under vacuum or in an inert gas stream to volatilize the unreacted ϵ−caprolactone from the polymer and cooling the vapor phase containing the matter which has been volatilized to thereby recover the unreacted ϵ−caprolactone, characterized in that the amount of the ϵ−caprolactone to be recovered is regulated to larger than 5 times by weight the amount of caprolactone dimer.
