摘要： The present invention relates to various embodiments of a system and method for separating polymer from a solvent. In one embodiment a system for separating polymer from a solvent comprises an extrusion apparatus includes a hollow member having a first end portion, a second end portion, and a feed port between the first end portion and the second end portion. The extrusion apparatus includes a back flash vent port disposed upstream of the feed port and a forward flash vent port disposed downstream of the feed port. The extrusion apparatus further includes a vent insert located at the forward flash vent port, a screw disposed inside the hollow member, and an internal superheating section disposed between the feed port and the downstream vent opening of the hollow member such that the length of the internal superheating section is greater than about four times the diameter, 4D, of the hollow member.
