Interpenetrating polymer networks: So happy together?

A typical description of interpenetrating polymer networks (IPN) can be surprisingly simple, systems that consist of two crosslinked polymer networks that are physically entangled but not chemically linked. That simplistic description, however, successfully encompasses a wide range of synthesis processes and macromolecular architectures that can include “semi-IPN” (IPN-like systems containing only one crosslinked polymer) and interconnected...
