    • A process for removing vaporizable constituents from high-viscosity solutions or melts of thermoplastics by continuous evaporation along a heated devolatilization zone and separation of the vapor phase from the liquid phase in a downstream separating vessel. The plastic solution or melt is first heated stepwise in increments, in the devolatilization zone, while the product is in the form of thin layers from about 0.5 to 4 mm, so as to maintain a temperature difference of less than 50.degree. C. between the heat transfer medium and the plastic solution or melt until the devolatilization temperature is reached, the distribution of the solution or melt to form thin layers of product taking place while the temperature conditions still correspond to those of the feed of solution or melt, after which the vaporizable constituents are evaporated so as to form a two-phase system of vapor and melt, and the heat of evaporation absorbed is substantially returned to the product during the evaporation along the devolatilization zone. The process permits the removal of vaporizable constituents under mild conditions.
