A modular device for the continuous degas sing of reaction products, such as of a carboxylic acid or a polycarboxylic acid with a multi-functional alcohol suitable for application in the production of precondensates (or also prepolymers), has a heated enclosure in which a plurality of modules are stacked one above the other, each said module having a base. There is a vapor inlet to the uppermost module and a discharge port at the lower most module with at least one module intermediate the uppermost and lowest modules to provide space for expansion of the vapor. The base of each module preferably is concave and there are conduits that provide flow communication between the modules.

Distributors for viscous fluids, consisting of a central inlet line and at least two valves that are connected radially to the inlet line, each valve having one valve spindle that moves in the axial direction in the cylindrical valve casing and an outlet opening that opens into an outlet line, whereby a flow displacer having a cylindrical bottom part and a conical top part is inserted centrally into the inlet line at the level of the valves, forming a ring gap, and where the cross section of flow is constricted in the outlet opening and then immediately thereafter is enlarged in the outlet line.
