Document Type and Number:
Japanese Patent JPS59202205
Kind Code:
A
Abstract:
A process for removing volatile constituents from polymer melts or pastes, wherein the polymer or paste containing the volatile constituents is passed, with continuous formation of fresh surfaces, through one or more zones in which the volatile constituents evaporate, and the volatile constituents are removed from the zone or zones in which they evaporate through, in each case, a plurality of porous orifices, and an apparatus for carrying out said process.
