Liquid Crystalline Epoxy Resin Modified Cyanate Ester/Epoxy Resin Systems
Liquid crystalline epoxy resin (LCE) modify cyanate ester/epoxy resin blend systems were studied by scanning electron microscope, polarizing optical microscope, thermogravimetric analyzer, differential scanning calorimetry,
thermal mechanical analysis, and rheometers. With the addition of LCE resin, the blends showed both an enhanced curing rate and increased glass transition temperature of cured...

Phase separation and rheological behavior in thermoplastic modified epoxy systems.
The relationship between rheological behavior and phase separation in polyesterimide modified epoxy systems was studied by rheometry, time-resolved light scattering (TRLS), and Differential Scanning Calorimetry (DSC). The rheological behaviors of blends during phase separation showed an exponential grow of complex viscosity, while the phase separation was inhibited by the vitrification of the poly...

Polymerization-induced viscoelastic phase separation in polyethersulfone-modified epoxy systems
The polymerization-induced phase-separation process of polyethersulfone (PES)-modified epoxy systems was monitored in situ continuously on a single sample throughout the entire curing process by using optical microscopes, time-resolved light scattering (TRLS), scanning electronic microscopes (SEM), and a rheometry instrument. At specific PES content a viscoelastic transformation process of phase i...

Effect of polyethersulfone on the mechanical and rheological properties of polyetherimide-modified epoxy systems.
The reaction-induced phase separation process of polyethersulfone- and polyetherimide-modified (PES- and PEI-modified) epoxy systems was investigated by using transmission electronic microscopes (TEM) and a rheometry instrument. The morphologies of cured blends alter considerably with the PES content and molecular weight at the same content of total thermoplastics. Compared with the PEI-modified s...
