Abstract
A crosslinked carboxylated polymer having ionic crosslinks.
Claims18
A crosslinked carboxylated polymer, comprising a carboxylated polymer having a plurality of carboxyl groups treated with an amount of an amine compound having at least one amino group reactive toward a carboxyl group of the carboxylated polymer to form an amide bond and at least one amino group that is reactive toward a carboxyl group of the carboxylated polymer to form an ionic bond.
A crosslinked carboxylated polymer, comprising a carboxylated polymer having plurality of crosslinks, each of the plurality of crosslinks comprising a first bond and a second bond, wherein the first bond is an amide bond formed between a carboxyl group of the carboxylated polymer and a first amino group of a crosslinking agent, and wherein the second bond is an ionic bond formed between a carboxyl group of the carboxylated polymer and a second amino group of the crosslinking agent.
