Interpenetrating Polymer Networks

Angewandte Chemie International Edition in English, 1978
AbstractBesides mechanical blending and copolymerization there is a third possible way in which two polymers can be combined. Each polymer forms its own network, while both networks interpenetrate each other. There are no covalent bonds between the polymers. Such interpenetrating networks have been synthesized sequentially (from polymer A and monomer B)

Topologically Interpenetrating Elastometric Networks

Rubber Chemistry and Technology, 1970
Abstract Several partially interpenetrating polymeric networks (IPN) were made by combining chemically different linear elastomers. The polymer combinations were deposited as films from aqueous emulsions made by mixing the individual emulsions in equal proportions. The films were crosslinked to form two superimposed networks.

Interpenetrating bimodal networks

Polymer Engineering & Science, 1985
AbstractSequential interpenetrating networks (IPN's) were obtained from a tetrafunctionally end‐linked network [prepared from hydroxyl‐terminated poly(dimethylsiloxane) (PDMS) chains having a number‐average molecular weight of 21.3 × 103 g mol−1] by swelling it with very short vinyl‐terminated PDMS chains (∼450 g mol−1), which were then themselves ...

Copolymers and Interpenetrating Networks

2015
Random copolymers are prepared by the copolymerization of a mixture of cyclic oligomers. Although the resulting polymer can be quite blocky (figure 8.1), taking the reaction to equilibrium can give a polymer that is essentially random in its chemical sequencing. One reason for preparing copolymers is to introduce functional species, such as hydrogen or

composites with interpenetrating networks

Scripta Metallurgica et Materialia, 1995
Homogenous microstructures of Ni3Al/A2O3 composites can be produced by gas pressure infiltration of the intermetallic phase into the porous ceramic. Since the nickel aluminide is single crystalline in the reinforcing ligaments, it exhibits ductile deformation and provides appreciable toughening for the composite.

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 ...
