Abstract
Process and apparatus for the continuous preparation of polymers Two reaction partners (starting materials) are stored in separate reservoirs 2, 3, 4 and 5 and are transported using overpressure via heated heat exchangers 11, 12 into a micromixer 18 by means of control and metering devices 6, 7, which can be metering pumps. In the heat exchangers 11, 12, the starting materials are heated, separately in each case, to the extent that during the mixing operation in the micromixer 18 the required reaction temperature is immediately reached. The polymerization takes place in a downstream tube reactor 20 which consists of tubes 21, 22, 23 which are connected in series.
