Abstract: PROBLEM TO BE SOLVED: To enable precipitate formation to be diminished due to too rapid polymerization of the subject monomer during its compression by conducting the compression in the presence of a sterically hindered amine derivative. SOLUTION: An ethylene-based unsaturated monomer is compressed under a pressure of 200-5,000 bar in the absence of any polymerization initiator but in the presence of a sterically hindered amine derivative. In this case, it is preferable that 0.0001-0.1wt.%, based on the monomer, of an N-oxyl compound of e.g. the formula (R is an alkyl, cycloalkyl, aralkyl, etc.) in combination with the amine derivative, the temperature during the compression is 20-140 deg.C, and an auxiliary stabilizer is used.

Abstract: A process is claimed for the compression of ethylenic monomers to a pressure of 200-5000 bar, carried out in the absence of a polymerisation initiator and in the presence of a sterically hindered amine derivative (I). Also claimed is (i) a process for the production of copolymers by compressing the comonomers as above and then polymerising at 50-350 degrees C with addition of initiator, and (ii) copolymers obtained by this process.
