Abstract
The present invention relates to a continuous high-pressure polymerization process for the preparation of a liquid ethylene copolymer which comprises in polymerized for methylene; and a reactive acrylate which is selected from hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, and hydroxybutyl (meth)acrylate, where a monomer feed comprising the ethylene and the reactive acrylate is polymerized in the presence of at least 2 wt % of a chain transfer agent. The present invention also relates to the liquid ethylene copolymer, to a coating material comprising the liquid ethylene copolymer and to a use of the liquid ethylene copolymer to produce a coating material.
