An Interpenetrating Polymer Network (IPN) is the normal form of two or more crosslinked polymers. These are water soluble networks and are rendered insoluble due to the presence of chemical or physical crosslinks. As IPNs have high water uptaking capacity and biocompatibility to natural tissues, these are used in biomedical and pharmaceutical applications like drug-delivery systems. Characteristics of IPNs like % swelling, number average molecular weight between crosslinks, mesh size, compressive strength vary when these are formed from different crosslinking agents and are allowed to swell...
