Diglycidyl ether of bisphenol-A epoxy

The matrices were two DGEB A (diglycidyl ether of bisphenol A) epoxy resins. The hardeners were either 35 parts by weight of diamino diphenyl sulfone (resin I) or 55 parts of polyamino amide (resin II). The curing conditions were 3 h at 130°C followed by 3 h at 180°C for resin I and 24 h at 40°C followed by 6 h at 100°C for resin II. [Pg.186]

Other quinoxaline-type polymers can have higher Tg values, e.g. 400°C. DGEBA stands for diglycidyl ether of bisphenol A. Epoxy resin properties can depend considerably on the hardener used. [Pg.22]

Epoxy resin ceiling temperatures depend crucially on both the epoxy resin and the hardener. The difunctional DGEBA (diglycidyl ether of bisphenol A) epoxy resin system is the most common, producing high heat distortion... [Pg.130]

The thermal properties of the nanocomposites of diglycidyl ether of bisphenol A epoxy resin containing different montmorillonite nanoclays depends on the surface modifications of the nanoclays. Moreover, the addition of nanoclays improved the thermal properties of the nanocomposites, compared to the neat epoxy [59]. [Pg.33]

The additive reaction of oxiranes was also utilized for the preparation of SMP networks with covalent crosslinks. The crosslinking of 3-amino-1,2,4-triazole with epoxidized natural rubber catalyzed by bisphenol-A resulted in polymer networks having shape-memory capability with Ti ms = Tg [82]. The Tg could be controlled by the 3-amino-1,2,4-triazole content in the range between 29 and 64 °C. Recently, the crosslinking reaction of oxiranes and amines was systematically investigated in two polymer systems based on the reaction of the diglycidyl ether of bisphenol A epoxy monomer cured with the bifunctional poly(propylene glycol)bis(2-aminopropyl)...

As a component of non-diglycidyl ether-of-bisphenol-A epoxy resins, brominated epoxy resin caused contact dermatitis in a cleaner of worksites in a condenser factory, in which condensers were filled with a mixture made of an epoxy resin. [Pg.1132]

Kim and Robertson [203] studied the toughening of an aromatic amine-cured diglycidyl ether of bisphenol A epoxy with particles of crystalline polymers. The crystalline polymers chosen were polyfbutylene terephthalate) (PBT), nylon-6, and polyCvinylidene fluoride) (PVDF). Each of these was found to be capable of un-... [Pg.436]

The most common epoxy resin is based on the diglycidyl ether of bisphenol A. Epoxy resins are sometimes esterified with fatty acids or modified with polyurethane intermediate chains for elastification. [Pg.35]
