摘要：
Compounds of the formula I, II, III or IV ##STR1## wherein X is halogen, OH, --OR.sup.1, --OOCR.sup.2, --OOC--R.sup.4 --COOR.sup.3 or --N(R.sup.5)(R.sup.6), or the two X groups together form a group --O--R.sup.9 --O-- or --OOC--R.sup.9 --COO--, Y has one of the meanings given for X, or it is --NHR.sup.5, --NHNH.sub.2 or --NHNH-phenyl, Z has one of the meanings given for X, or is --SR, and R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.9 and R' are organic radicals having the meanings defined hereinbelow, are thermal stabilizers for chlorine-containing thermoplastics particularly for PVC. Their effect can be further intensified by the addition of co-stabilizers.
