Abstract: A process for the preparation of copolymers of ethylene with acrylic esters (acrylates) by copolymerisation of 100 parts by weight of ethylene with from 0.1 to 25.0 parts by weight of acrylic esters in a continuous, tubular polymerisation system at pressures of from 500 to 4,000 bar and temperatures of from 100 to 400 DEG C in the presence of polymerisation initiators which decompose to form free radicals, where the temperature regime for the reaction mixture comprising ethylene, acrylic esters, polymerisation initiators and optionally regulators after entry into the reaction zone is designed in such a way that the quotient dT/dt (increase in temperature per time unit) is kept constant at a value between 1.5 and 2.5 DEG C per second.
