ABSTRACT:
Thermoplastic, high-molecular-weight material which can be processed in the melt and which contains at least one nickel complex derived from a ligand of the formula I ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4, independently of one another, are --H, halogen or --CH.sub.3, R.sub.5 and R.sub.6, independently of one another, are --H or C.sub.1 -C.sub.4 alkyl, A is a para-phenylene radical of the formula II or a mixture of a para-phenylene radical of the formula II with an orthophenylene radical of the formula III ##STR2## the proportion of ortho-phenylene radical in the mixture being not more than 60% by weight, and X.sub.1 and X.sub.2, independently of one another, are --H, halogen, --CH.sub.3, --OCH.sub.3 or --OC.sub.2 H.sub.5, and Y.sub.1 and Y.sub.2, independently of one another, are --H, halogen, --CH.sub.3 or --OCH.sub.3, or Y.sub.1 is a radical of the formula ##STR3## and Y.sub.2 is --H, or Y.sub.1 and Y.sub.2 together are --NHCONH-- or --CONHCO--, where R.sub.7 is --H or C.sub.1 -C.sub.4 alkyl and R.sub.8 is --H, halogen, --CH.sub.3 or --OCH.sub.3.
