Interpenetrating Polymer Networks for Biological Applications

Biomaterials, Medical Devices, and Artificial Organs, 1979
The use of a sequential polymerization method for preparing interpenetrating polymer networks with biocomatible surfaces has been studied. A hydrogel monomer was made to undergo polymerization with simultaneous cross-link formation, in the presence of a swollen thermoplastic elastomer heterophase block copolymer.

Interpenetrating polymer networks

British Polymer Journal, 1985
AbstractInterpenetrating polymer networks (IPNs) composed of two or more chemically distinct networks are not only intrinsically interesting as examples of macromolecular chemical topological isomerism but are in practice useful means of controlling mutual miscibility and phase morphology in crosslinked polymers.

Interpenetrating Polystyrene Networks

2011
Publisher Summary This chapter provides a detailed description of interpenetrating polystyrene networks (IPNs). IPNs are composed of two or several chemically independent crosslinked polymers that present an important family of polymeric materials.

Nomenclature of Interpenetrating Polymer Networks

Journal of Elastoplastics, 1973
A nomenclature scheme for various types of interpenetrating polymer networks (IPN) based on morphology, topology, and method of synthesis is presented. In this scheme, IPN is the generic name of all polyblends of this type, regardless of their origin, as opposed to Sperling's recent classification of polyblends and graft copolymers, (Polymer Preprints,

Topologically Interpenetrating Polymeric Networks

Journal of Elastoplastics, 1971
This article describes ways of producing interpenetrating poly meric networks (IPN's). Formation of IPN's is one method used in overcoming the difficulty in mixing chemically incompatible poly mers. One method of preparing IPN's is the sorption of liquid curable polymers by crosslinked polymer films, then curing the resultant swollen film.

Interpenetrating and pseudo-interpenetrating polymer networks of polyethylacrylate and zeolite 13X

Journal of Polymer Science Part A: Polymer Chemistry, 1996
Free radical polymerization of liquid ethylacrylate in the presence of zeolite 13X yielded PIPNs without crosslinker and IPNs if the crosslinker ethylene glycol dimethacrylate was present. We studied these materials both unextracted as well as partially extracted with a variety of solvents using DSC, SEM as well as Small Angle X-ray Scattering (SAXS ...

Recent Advances in Interpenetrating Polymer Networks

Polymer Engineering & Science, 1984
AbstractInterpenetrating polymer networks (IPN's) can be defined as a combination of two polymers in network form, at least one of which was synthesized and/or crosslinked in the immediate presence of the other. Historically, the science of IPN's began with the papers of J. R.

Polyester-polyurethane interpenetrating networks

European Polymer Journal, 1977
Abstract Several two-component interpenetrating networks based on a polyester and a polyurethane were prepared. Some of these materials showed rigidity moduli higher than those of the component networks. Each interpenetrated network has only one glass transition temperature, indicating a high dispersion. Damping properties were also studied.
