Curing studies of epoxy resins with phosphorus‐containing amines

摘要: The curing system of diglycidyl ether bisphenol A (DGEBA) with two phosphorus-containing amine compounds—bis(3-aminophenyl)methyl phosphine oxide and bis(4-aminophenyl)-bis(9,10-dihydro-9-oxa-10-oxide-10-phosphaphenanthrene-10-yl)methane—was studied differential scanning calorimetry under isothermal nonisothermal conditions compared the DGEBA/diamino diphenyl methane system. isoconversional method was used to evaluate dependence effective activation energy on extent conversion. Modulated dynamic mechanical thermal analysis were study phenomena vitrification gelation. flame-retardant properties evaluated, limiting oxygen index values phosphorylated resins, above 30, confirmed that epoxy resins are flame retardants. © 2006 Wiley Periodicals, Inc.
