摘要： Compounds of the formula: ##STR1## wherein n is 1, 2, 3, or 4; X.sup.1 and X.sup.2 are each, independently, chlorine or bromine; A is O or S; R.sup.1 is hydrogen or C.sub.1 -C.sub.16 alkyl; R.sup.2 is C.sub.1 -C.sub.16 alkyl, C.sub.6 -C.sub.16 aryl, C.sub.1 -C.sub.4 alkylidene, or CH.sub.2 OR.sup.5 ; R.sup.3 is hydrogen, chlorine, bromine, or OR.sup.6 ; R.sup.4 is C.sub.1 -C.sub.16 alkyl, C.sub.7 -C.sub.16 aralkyl, C.sub.2 -C.sub.16 alkenyl, or C.sub.6 -C.sub.18 aryl; R.sup.5 is hydrogen, C.sub.1 -C.sub.16 alkyl, C.sub.7 -C.sub.16 aralkyl, C.sub.2 -C.sub.16 alkenyl, or C.sub.6 -C.sub.18 aryl; and R.sup.6 is hydrogen or C.sub.1 -C.sub.16 alkyl. These compounds by themselves and in combination with certain halo-but-2-enoic acids and esters are useful as catalyst promoters in ethylene polymerization processes.
