摘要： A shell-and-tube heat exchanger, for removing volatile substances from a polymer solution by degasification, includes a bundle of tubes arranged vertically and parallel to each other in a shell chamber through which a fluid heat-transfer medium flows. The upper end of each tube is fixed in an upper tube sheet and the lower end of each tube is fixed in a lower tube sheet, and the polymer solution flows through the tubes in the direction of gravity. One feature is that a multilayer woven wire fabric is attached to the top of the upper tube sheet. The finest meshed layer of the fabric has a mesh width of 50 μm to 1000 μm. The invention also relates to a method for removing volatile substances from a polymer solution by degasification in a shell-and-tube heat exchanger and use of the shell-and-tube heat exchanger.

摘要： A polybutadiene latex is prepared by a process in which butadiene is polymerized by free radical emulsion polymerization in the presence of initiator and, if required, dispersants and further conventional assistants, the polymerization being carried out in the presence of reactive comonomers in such a way that the heat flow of 43 watt/kg solids content of the polymerization mixture is not exceeded. Owing to the presence of reactive comonomers, the reaction rate at the beginning of the reaction is increased, with the result that an overall flatter heat flow profile is obtained. A preferred reactive comonomer is styrene. Preferably, the process is carried out by a semi-batch procedure in which (a) in a first stage, a portion of butadiene and at least one portion of reactive comonomer in the form of an aqueous emulsion are initially taken with a thermal polymerization initiator and, if required, dispersants and further conventional assistants and the polymerization is initiated, (b) in a second stage, the remaining amount of butadiene and, if required, the remaining amount of reactive comonomer are added undiluted or in the form of an aqueous emulsion, if required with dispersants and, if required, further conventional assistants, as a feed.

摘要： A process for the salt-free coagulation of polymer dispersions in a rotor/stator assembly is disclosed. The rotor/stator assembly includes a casing, a rotor shaft rotatably mounted within the casing, a rotor having a conical surface affixed to the rotor shaft, and a stator affixed to the casing and concentrically associated with the rotor. The conical surface faces a surface of the stator to form an adjustable shear gap, which is surrounded by an annular space. A polymer dispersion is fed into the assembly and conveyed through the shear gap. During this conveyance, the polymer dispersion is precipitated at a predetermined shear rate and a predetermined shear deformation. The polymer dispersion is discharged from the assembly through an outlet neck, and the assembly is flushed with water using one or more ports formed in at least one of a pipeline coupled to the axial feed neck, the stator, and the casing.
