The effect of reaction-induced micro-phase separation of block copolymer on curing kinetics of epoxy thermosets
ABSTRACT: The curing kinetics of epoxy system modified with Poly(ε-caprolactone)-block-Polystyrene (PCL-b-PS) diblock copolymer was investigated by differential scanning calorimetry(DSC). PCL-b-PS was synthesized Via the combination of ROP and ATRP, then incorporated into epoxy to access the nanostructured thermosets. The results of TEM, SAXS and DSC demonstrated the occurrence of Reaction-indu...

Effect of borates on thermal degradation and flame retardancy of epoxy resins using polyhedral oligomeric silsesquioxane as a curing agent
A series of flame-retardant epoxy resins containing boron and silicon were obtained through a crosslinking reaction, using tris (2-hydroxypropyl) borate (THPB) together with octaaminophenyl POSS(OapPOSS) as the curing agents. The limiting oxygen index (LOI) reached 30.5% when the contents ofboron and silicon in the cured system were 1.5% and 0.5%, respectively, indicating that THPB and OapPOSS exh...

Comparison of hydrogenated bisphenol A and bisphenol A epoxies: curing behavior, thermal and mechanical properties, shape memory properties
Hydrogenated bisphenol A epoxy resin was cured using different kind of curing agents,
resulting in epoxy networks with better shape memory properties than bisphenol A epoxy networks. The non-isothermal curing kinetics investigated by differential scanning calorimetry (DSC) demonstrated that hydrogenated bisphenol A epoxy showed lower curing reactivity than bisphenol A epoxy, while it stil...
