Abstract
(EN)
The present invention relates to a method for manufacturing a crosslinker compound, wherein a crosslinker compound usable for the manufacture of a super absorbent polymer can be obtained with a higher yield in a simple way. The crosslinker compound obtained by such a method can be preferably used as a thermally decomposable internal crosslinker in the manufacturing process of the super absorbent polymer.
