    摘要: Compounds corresponding to the following general formula: ##STR1## wherein R.sup.0 represents H or, together with R.sup.1, represents --CO-- when X represents --CO-- or, together with R.sup.2, represents --CO-- when X represents --CH.sub.2 --CO,a residue of R, R.sup.1 and R.sup.2, H, C.sub.1 -C.sub.4 alkyl, aryl, COOR.sup.5 or, when R.sup.0 represents H and X represents --CO--, ##STR2## and the other residues R, R.sup.1 and R.sup.2 represent H; R.sup.3 represents H or CH.sub.3 ;R.sup.4 represents C.sub.7 -C.sub.20 aralkyl;R.sup.5 represents H, C.sub.1 -C.sub.4 alkyl or C.sub.6 -C.sub.12 aryl;X represents a residue --(CH.sub.2).sub.n CO--, --(CH.sub.2).sub.n SO.sub.2, --CH.sub.2 --, --CH.sub.2 O--CO-- ##STR3## m represents 1 or 2; and n represents 0 or 1;are suitable for use as incorporable antiagers for polymers, particularly nitrile rubber.
