Polyboronic Compounds and Processes of Making and Using the Same

摘要

Polyboronic compounds useful as delayed crosslinking agents may be produced by using a polyamine as base scaffold and incorporating boron via reaction with intermediate borates which may be formed in the condensation reaction between boric acid and a diol. A di-aldehyde, such as glyoxal, may be introduced following caustic treatment of the reaction mixture of polyaminoboronate to form the polyboronic compound.
