    Abstract: HOE 89/F 353 Process for the preparation of alternating copolymers prepared from unsaturated polar compounds and olefins The invention relates to a process for the preparation of alternating copolymers from unsaturated polar compounds and olefins in the presence of complexing agents, in which the complexing agent comprising the primarily formed copolymer/metal compound complex can be recovered in a simple manner and in reusable form. The copolymerization is carried out in the presence of salts, such as nitrates, but preferably halides, of divalent metal ions as the complexing agent in organic solvents at pressures of up to about 100 bar and at temperatures between -78.degree.C and 100.degree.C with the use of free-radical initiators. The reaction product is a mixture of the copolymer of a strictly alternating structure of unsaturated polar compounds and olefin, and of a copolymer which is higher in the unsaturated polar compound. The alternating copolymer can be easily separated therefrom by extraction with solvents, such as trichloromethane or acetone.

    Abstract: The present invention relates to compounds of the formula in which R and R are identical or different and stand for hydrogen or an alkyl radical having 1 to 18 carbon atoms optionally containing oxygen, nitrogen or halogen, the radicals X, Y and Z are identical and stand for a fluorine, bromine or iodine atom or, if two of the radicals X, Y or Z are identical or all the radicals X, Y and Z are different from one another, X, Y and Z denote a fluorine, chlorine, bromine or iodine atom. The invention further relates to a process for the preparation of the compounds by reacting an aryldiazonium salt of the formula in which the radicals X, Y and Z are identical and stand for a fluorine, bromine or iodine atom or, if two of the radicals X, Y and Z are identical or all the radicals X, Y and Z are different from one another, X, Y and Z denote a fluorine, chlorine, bromine or iodine atom and A denotes an anion of an acid having a pKa of in which R and R are identical or different and stand for hydrogen or an alkyl radical having 1 to 18 carbon atoms optionally containing oxygen, nitrogen or halogen, in the presence of a palladium-containing catalyst, if appropriate with addition of a base, and to the aryldiazonium salts of the formula (II).
