“…An epoxy resin containing a cyclic phosphine oxide group in the main chain (Scheme )133 and a tetrafunctional epoxy containing phosphorus oxide and nitrogen groups in the main chain (Scheme )134 were synthesized and cured with bis(3‐aminophenyl)methylphosphine oxide (BAMP), 4,4′‐diaminodiphenylmethane (DDM) or 4,4′‐di‐aminodiphenyl sulfone (DDS), and compared with commercial resins. In any combination, either cured with phosphorus‐containing BAMP, DDM or DDS, the phosphorus‐containing epoxy resins showed higher char yields than bisphenol A or novolac‐type commercial resins.…”

“…A few studies have been reported in the literature concerning curing of epoxy resins with bis(aminophenyl)methylphosphine oxide (Scheme ), as well as the thermal and combustion performance of the resins containing this oxide 56, 87, 133, 149–153. Von Gentzkow et al 129 have used the analogous bis(aminophenyl)ethylphosphine oxide (Scheme ) to cure a phosphorus‐containing epoxy resin.…”

An overview of the recent literature on combustion and flame‐retardancy of epoxy resins is presented. A brief overview of the structures of cured epoxy resins is also presented as a background for better understanding of the thermal decomposition and combustion phenomena. The literature sources were mostly taken from the publications of 1995 and later; however, for basic descriptions of the structural and thermal decomposition principles, older publications are also cited. New developments in flame‐retardant additives, epoxy monomers and curing agents are described. It is shown that the main attention in recent years has been focused on phosphorus‐containing epoxy monomers and epoxy resins. Silicon‐containing or nitrogen‐containing products and inorganic additives remain of great interest as supplementary materials to phosphorus flame‐retardants.

Abstract.A novel curing agent Thoreau modified 3, 5-Dimethyl-thioltoluenediamine was synthesized and its molecular structure was characterized by FTIR and DSC. The curing kinetics of a high toughness and low volume shrinkage ratio epoxy system (modified DMTDA/DGEBA) was studied by differential scanning calorimetry (DSC) under noni so thermal conditions. The data were fitted to an order model and autocatalytic model respectively. The results indicate that in order model deviates significantly from experimental data. Malik's method was used to prove that the curing kinetics of the system concerned follow single-step autocatalytic model, and a "single-point model-free "approach was employed to calculate meaningful kinetic parameters. The DSC curves derived from autocatalytic model gave satisfactory agreement with that of experiment in the range 5K/min~25K/min. As the heating rate increased, the predicted DSC curves deviated from experimental curves, and the total exothermic enthalpy declined owing to the transition of competition relationship between kinetics control and diffusion control. IntroductionEpoxy resin is one of the most important thermosetting resins. The cured epoxy resins are of high crosslinked network that often exhibit high tensile strength and modulus [1], excellent chemical and corrosion resistance [2], and good thermal stability [3]. However, the ordinary epoxy resin cannot crosslink alone without curing agents or accelerant. In order to convert the resins to practical materials, it is necessary to add a curing agent. Most of the epoxy curing agents in common use are ploy functional amines [4,5], tertiary amines, anhydrides and other latent curing agents. Now with theorem can significantly reduce the curing temperature of epoxy resin, to synthesis a novel curing agent by theorem-polyamine condensation reaction, the study using theorem modified liquid aromatic amine, the expected good mechanical properties of the resin system.In this paper, 3, 5-Dimethyl-thioltoluenediamine (DMTDA) was used to replace the solid aromatic amines, and the amount of active hydrogen in theorem was more than that of solid urea and polyamine. , After the reaction can improve the reactivity of DMTDA, make it better and more fully with the epoxy resin reaction. The final preparation of low toxicity, faster curing, and epoxy resin easy to mix evenly epoxy curing agent.
