Interpenetrating polymer networks (IPNs) are a combination of two or more polymers in networks where a partial interlacing on the molecular scale is present in the matrix.
There is no covalent bonding and therefore the polymers cannot be separated unless the chemical bonds are broken (Fig.
).Thus the mixtures of two prepared polymers, networked without any interlacing, are not generally.
