Materials known as interpenetrating polymer networks, IPN s, contain two or more polymers, each in network form (6 9), A practical restriction requires that at least one of the polymer networks has been formed (i.e. polymerized or crosslinked) in the immediate presence of the other. Two major types of synthesis have been explored, both yielding distinguishable materials with different morphologies and physical properties.

Abstract This article summarizes a large amount of work carried out in our laboratory on polysiloxane based Interpenetrating Polymer Networks (IPNs). First, a polydimethylsiloxane (PDMS) network has been combined with a cellulose acetate butyrate (CAB) network in order to improve its mechanical properties. Second, a PDMS network was combined with a fluorinated polymer network. Thanks to a perfect control of the respective rates of formation of each network it has been possible to avoid polymer phase separation during the IPN synthesis. Physicochemical analyses of these materials led to classify them as true IPNs according to Sperling s definition. In addition, synergy of the mechanical properties, on the one hand, and of the surface properties, on the other hand, was displayed. 

This brief introduction to the synthesis and general properties of interpenetrating polymer networks demonstrates that IPNs are complex multicomponent polymer...

Our research with the SLMs has centered on the synthesis of highly stable membranes for long term metal ion transport. Since it is advantageous to maintain polypropylene as the basic support structure due to its commercial availability, a versatile membrane modification technique has been found to be that involving interpenetrating polymer networks [IPNs]... 

All interpenetrating polymer networks utilize two different polymers. The exception involves the homo-IPNs, where both polymers are identical [Millar, 1960 Siegfried et al., 1979]. While these polymers may be synthesized by any of the known methods of polymer synthesis, some methods clearly work better in given objectives than others. The principal kinetic methods used are chain and step polymerization.

An interpenetrating polymer network (IPN) is an intimate assembly of two polymers in network form, one of which is usually either prepared or crosslinked in the presence of the other. Typically, the initial polymer network is. swollen in the presence of the second monomer together with a crosslinking agent, and the second monomer allowed to polymerise and crosslink. Alternatively, simultaneous. synthesis is possible in which the monomeric components of both networks are first mixed and then allowed to polymerise.
