interpenetrating polymer network (IPN)

https://doi.org/10.1351/goldbook.I03117
Polymer comprising two or more networks that are at least partially interlaced on a molecular scale but not covalently bonded to each other and cannot be separated unless chemical bonds are broken.
Note:
A mixture of two or more preformed polymer networks is not an IPN.
