Claim 0:
1. A middle-pressure polymerization process for the preparation of an ethylene copolymer which is liquid at room temperature which comprises in polymerized form
20 to 60 wt % of ethylene; and
at least 20 wt % of an acrylate, which comprises
a polar acrylate selected from C1-C5 alkyl (meth)acrylate, and
an unpolar acrylate selected from C6-C22 alkyl (meth)acrylate,, where a monomer mix comprising the ethylene and the acrylate is polymerized at a pressure of 50 to 400 bar and in the presence of at least 2 wt % of a chain transfer agent, where the percentage of the chain transfer agent is based on the sum of the amounts of monomers and the chain transfer agent.
