Anharmonicity and fragility in semi-interpenetrating polymer networks

Journal of Physics: Condensed Matter, 2000
Two series of semi-interpenetrating polymer networks (semi-IPN) based on the same linear polyurethane and two different heterocyclic polymer networks were characterized in terms of the complex dynamic modulus and the mechanical loss tangent, measured between 150 and 500 K at a frequency varying in the range between 0.3 and 30 Hz.

Structural and rheological properties of chitosan semi-interpenetrated networks

The European Physical Journal E, 2010
The local structure and the viscoelastic properties of semi-interpenetrated biopolymer networks based on cross-linked chitosan and poly(ethylene oxide) (PEO) were investigated by Small Angle Neutron Scattering and rheological measurements. The specific viscosity and the entanglement concentration of chitosan were first determined, respectively, by ...

A SEMI-INTERPENETRATING NETWORK SYSTEM FOR A POLYMER MEMBRANE

European Polymer Journal, 1997
Abstract A semi-interpenetrating network has been prepared for a polymer membrane. The first network consists of sodium alginate which provides the crosslinked network. The other is polyacrylic acid or polyacrylamide which imparts its characteristic into the polymer network.

Semi-Interpenetrating Networks of Sulfur-Containing Bismaleimides

High Performance Polymers, 1993
Microphase-separated semi-interpenetrating polymer networks (semi-n Ns) were obtained by curing 4,4'-bismaleimidodiphenylmethane (BMII), which was advanced in situ with diamine-terminated oligo(phenylene sulfide) (PPS-DA), in the presence of a non-crosslinked linear high-T, aromatic polyether.
