Abstract: The invention relates to a method for polymerizing acrylates using a reactor (50). Reaction heat produced in the reactor (50) is discharged via a boiling cooler (40) in that gaseous vapors produced in the reactor (50) are supplied to the boiling cooler (40), and condensed vapors are returned to the reactor (50) from the boiling cooler (40). At least one component containing acrylate is at least partly added via the boiling cooler (40) and reaches the reactor (50) via the boiling cooler (40). The invention additionally relates to a system for polymerizing an acrylate, comprising a reactor (50) and a boiling cooler (40) for discharging reaction heat produced in the reactor (50). The boiling cooler (40) has at least one filling opening (46) for supplying at least one component containing acrylate.
