Abstract
An improved polymerization reactor apparatus having a vertically disposed outer shell, a liquid polymer inlet at the top of the shell and a liquid polymer outlet at the bottom of the shell, and a series of downwardly sloping trays for conducting a flow of the liquid polymer in a descending path from the inlet to the outlet; the series of trays being encompassed within a series of essentially rectangular pan assemblies supportedly spaced inwardly from the outer shell and by which pan assemblies the liquid polymer flow is divided into two separated flows of uniform flow cross-section, with vapor from the liquid polymer escaping along paths separated from interference with the liquid polymer flow paths from the open top of each pan assembly and through 'windows' or openings in two of the opposite end walls of the pan assembly to the outer shell of the reactor apparatus.
