The effect of a curing agent on the thermal degradation of fire retardant brominated epoxy resins

A quantitative study of carbon monoxide and carbon dioxide evolution during thermal degradation of flame retarded epoxy resins

“…They act in vapour phase, producing free radicals which interact with decomposing polymers and reduce the degradation. The early degradation observed for the halogenated flame retardant system could be due to dehydration and chain scission by mechanism initiated by the Br group initiating reaction leading to HBr formation [36].…”

Effect of functionalized kaolinite on the curing kinetics of cycloaliphatic epoxy/anhydride system

“…The properties of the epoxy resin strongly depend on their chemical structure, the extent of curing, the clay mineral-polymer compatibility, as well as the curing conditions (Balabanovich et al, 2004;Cizmecioglu et al, 1986;McIntyre et al, 2005;Naito and Todd, 2002). Therefore, in order to understand and control better the cure process, and optimization of the properties of the final product, it is essential to trace exactly the relationship between structure and properties of the epoxy resin system.…”

Characteristics of exhaust gas, liquid products, and residues of printed circuit boards using the pyrolysis process

“…The pyrolytic process is an opportunity to recycle PCBs instead of sending them to landfill, incinerating them, and disposing of them by other methods. Pyrolysis has been employed to recycle brominated PCBs and obtain the compositions of PCBs (Chen et al 1997(Chen et al , 1999Chien et al 2000), pyrolytic kinetics (Barontini et al 2005;Chen et al 1997Chen et al , 1999Luda et al 2002;Balabanovich et al 2004), and brominated compound formation and fate (Barontini et al 2005;Chien et al 2000;Luda et al 2002;Balabanovich et al 2004;Blazsó et al 2002). Few studies have focused on PCB pyrolytic temperatures, the metal contents in pyrolytic by-products, the exhaust gas during the recycle, and pollution control procedures.…”
