Abstract: The invention relates to a method for producing a polymer from a first component and a second component by means of a reactor (50), wherein reaction heat in the reactor (50) is discharged via an evaporative cooler (40), wherein gaseous exhaust vapour in the reactor (50) is supplied to the evaporative cooler (40), and condensed exhaust vapour is guided from the evaporative cooler (40) back into the reactor (50). In this way, the first component and/or second component are supplied at least partially via the evaporative cooler (40) and moved from the evaporative cooler (40) into the reactor (50). The invention also relates to a system for producing a polymer, comprising a reactor (50) and an evaporative cooler (40) for discharging reaction heat in the reactor (50). In addition, the evaporative cooler (40) has at least one filling opening (46) for filling in the first and/or second component.

Abstract: Process for the preparation of styrenic polymers having an improved color stability by anionic polymerization wherein the obtained terminated polymer solution is fed to a dispersing device to which water is added, fed to a buffer vessel and then is impregnated in a static mixer by addition of further water, carbon dioxide and one or more stabilizers.
