Latex Interpenetrating Polymer Networks

International Journal of Polymeric Materials and Polymeric Biomaterials, 1972
Abstract Latex interpenetrating polymer networks are a unique type of polymer blend, synthesized by swelling crosslinked seed latex particles of polymer I with monomer II, plus cross-linking agents, and polymerizing monomer II in situ. In a manner similar to polymer blends generally, polymer 1 and II are incompatible to greater or lesser extents, and ...

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.

Swollen interpenetrating polymer networks

Polymer, 2000
Abstract The swelling in common (benzene) and selective (CCl4) solvents and small angle X-ray scattering (SAXS) of interpenetrating polymer networks (IPNs) of PPO/PMMA in all composition intervals are studied. It is shown that in both solvents IPNs swell better than the pure crosslinked polymers; that may be caused by a smaller degree of crosslinking

Interpenetrating Polymer Networks

Composite Interfaces, 2010
Interpenetrating polymer networks (IPNs) are a new class of polymer blends in network form in which at least one component is polymerized and/or cross-linked in the immediate presence of the other. IPNs possess several interesting characteristics in comparison to normal polyblends, because the varied synthetic techniques yield IPNs of such diverse ...

Functional Semi‐Interpenetrating Polymer Networks

Macromolecular Rapid Communications
AbstractSemi‐interpenetrating polymer networks (SIPNs) have garnered significant interest due to their potential applications in self‐healing materials, drug delivery systems, electrolytes, functional membranes, smart gels and, toughing. SIPNs combine the characteristics of physical cross‐linking with advantageous chemical properties, offering broad ...

RIM Systems From Interpenetrating Polymer Networks

Journal of Cellular Plastics, 1982
Simultaneous interpenetrating polymer networks (SIN-IPN’s) based on polyurethane and polyepo×ides were synthesized according to the processing conditions of RIM technology. Catalytic systems were selected in order to minimize or avoid formation of any covalent bonds between the epoxy and the polyurethane chains.

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.

Tough Interpenetrating Polymer Networks

1989
Interpenetrating polymer networks (IPN's) based on crosslinked rubbers and polystyrene have been synthesized. Mechanical properties and fracture toughness have been measured. IPN's based on highly crosslinked rubbers were found to be the most ductile and the toughest, these properties being much greater than for polystyrene homopolymer.

Topologically Interpenetrating Polymer Networks

1974
Ever since the concept of chemical topology was introduced,1 a number of investigators have prepared molecules showing topological isomerism,2–16 most of which were catenanes, i.e., interlocking rings with no chemical bonds between them, shown below.
