Abstract:
A process for preparing copolymers of ethylene with from 1 to 30 mol % of (meth)acrylates and, optionally, with other comonomers, and a residual comonomer content of less than 0.5% by weight in the copolymer, which comprises carrying out the polymerization in a combination of stirred autoclave and downstream tubular reactor byfirst polymerizing the monomer mixture in a stirred autoclave in a first stage at a temperature less than 200Â° C. then, in a second stage, continuing the polymerization in a tubular reactor at a temperature higher than 200Â° C. in the second stage, wherein the conversion in the first stage is at least 95% by weight based on the total weight of final product and the second stage is not more than 5% by weight.
