The hydrogels are network polymeric materials that exhibit the ability to absorb huge volumes of water, by swelling and not dissolving.
The liquid prevents the network from collapsing into a compact mass while the network prevents the liquid from flowing away. They consist of hydrophilic crosslinked macromolecules forming a three-dimensional and tangled network. Those have received attention in the past few years as materials for biological, biomedical, pharmaceutical and agricultural applications, though much attention is focused on their use as a controlled release system for drugs, bioactive agents or pesticides, incorporating them into a hydrogel as carrier. For every these applications, the knowledge of the swelling, the diffusion processes, the networks parameters that define its structure and reologycal properties in different conditions are very important since they will define their possible applications. In this work we present the synthesis of new hydrogels based in a new dendritic monomer (synthesized in our laboratory) with different amount of crosslinking agent. Besides, the studies of their properties thinking in useful application were examined.
