Abstract
Aqueous solutions of polygalactomannans are cross-linked with the reaction product of titanium tetrachloride and a water-soluble alcohol or diol further reacted with ammonia or a water-soluble amine. Such crosslinked products are useful in fracturing solutions for secondary oil recovery or in gel explosives.
