Abstract: A process for the compression of ethylenically unsaturated monomers at a pressure of 200-5,000 bar in the absence of a polymerization initiator is carried out in the presence of a nitroxyl compound (I). A process for the condensation of ethylenically unsaturated monomers at a pressure of 200-5,000 bar in the absence of a polymerization initiator is carried out in the presence of a nitroxyl compound of formula (I). Independent claims are included for: (i) a process for the production of copolymers by condensation of the comonomer, optionally as a mixture in the presence of (I) followed by polymerization at 50-350 degrees C by addition of a polymerization initiator; (ii) the resulting copolymer product. R , R = 1-4C alkyl or R and R together with the C atom they are bonded to form a 5 or 6 C saturated hydrocarbon ring; R = 1-4C alkyl; R = H or 1-12C alkyl.

Abstract: Inhibitor composition contains at least one nitroxyl radical (derivative), at least one phenol (derivative) and at least one other chemical compound containing phosphorus (P) atom(s). Inhibitor composition contains: (a) at least one nitroxyl radical (derivative) (I); (b) at least one phenol (derivative) (II); and (c) at least one other chemical compound (III) containing phosphorus (P) atom(s) with oxidation number +3. An Independent claim is also included for mixtures containing compound(s) with vinyl unsaturated group(s) and the inhibitor composition.
