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: A process for the production of oxidised polyolefin wax (I) comprises the continuous reaction of polyolefin wax (II) with oxygen or oxygen-containing gas at 140-200 degrees C and 5-200 bar in a tubular reactor, excluding polyolefins obtained by metallocene catalysis. Also claimed is oxidised polyolefin wax (I) obtained by this process, preferably with an acid number of 10-50.
