Abstract
A process for polymerizing or copolymerizing ethylenically unsaturated monomers at pressures in the range of from 110 MPa to 500 MPa in a production line comprising a continuously operated polymerization reactor which is installed within a protective enclosure, wherein the production line is monitored with respect to an occurrence of a leakage of monomers or of reaction mixture and a water based deluge system, which provides droplets of a diameter in a range from 25 μm to 20 mm to the enclosed area, is automatically started with a minimum flow rate of 10 L/min per mof enclosed area when a leakage of monomers or of reaction mixture is detected.
