The copolymers of functionalized polydimethylsiloxane (PDMS) and epoxy resin were prepared by varying the concentration of PDMS with an objective to produce products with high-performance properties. These copolymers were cured using polyamide as a curing agent and characterized by FT-IR. The thermal properties and completion of curing were checked by DSC. The copolymers were evaluated for electrical and mechanical properties. The dielectric strength of the material increases with decrease in dissipation loss and dielectric constant. The mechanical properties were improved by 30–40 percent. The main objective was to reduce the brittleness and improve impact strength of epoxy systems.

Hyperbranched poly(trimellitic anhydride butylene glycol)ester epoxy (HTBE) has relatively low viscosity and high molecular mass and holds great promise as a functional additive for enhancing the strength and toughness of thermosetting resins. The effect of molecular mass or generation and content of HTBE on the activation energy, reaction order, and curing time was discussed using DSC and TG techniques. The results indicated that HTBE could accelerate the curing speed and reduce the activation ...

Cyclohexanone-formaldehyde (CHF) resin was brominated and the brominated CHF (BCHF) was then reacted with excess aromatic diamines. The aminated CHF resins designated as ACHFs (modified ketone resin) were characterized and then applied as epoxy resin curing agents. Thus, the curing of the commercial epoxy resin diglycidil ether of bisphenol-A (DGEBA) by ACHFs was monitored by differential scanning calorimetric (DSC), based on the the DSC scans, the glass fiber-reinforced composites of DGEBA-ACHF...

The dielectric properties of a curing epoxy/amine system have been studied from 25 to 120 °C at 2.45 GHz. The epoxy resins at different extents of curing exhibit a γ relaxation, which can be described by the Arrhenius rate law. The relaxation is attributed to the motions of the dipolar groups associated with the crosslinking system. A simple model is proposed to represent the temperature dependence of the dielectric properties. A complete description of the evolution of the parameters during the...

ABSTRACT Diamines having heterocyclic ring, 4,5-bis (4-aminophenyl)-2-phenyl-imidazole (BAPI), 4,5-bis(4-aminophenyl)-2-methyloxazole (BAPO) and novel diamine, 2,3-bis(4-aminophenyl)benzo[g]quinoxaline (BABQ) were prepared as curing agents for epoxy resin. Epoxy resins were obtained by curing diglycidyl ether of bisphenol A (DGEBA) with the above diamines. Properties of these DGEBA-diamine systems were studied and compared to that of DGEBA cured with commercially available diamine, 4,4′-diaminod...

The dielectric properties of a diglycidyl ether of bisphenol A (DGEBA) epoxy resin and n-butylamine have been studied in the frequency range 100 Hz to 3 GHz at 25 °C. The unreacted mixture showed a single relaxation which gradually split in two relaxations, the separation of which increased as the reaction progressed. The low and high frequency relaxations are attributed to the structural dynamics of the growing macromolecules and to the motions of the dipoles associated with the monomers, respe...

Abstract The curing reactions of the epoxy resin 2,7-bis(4-N,N-diglycidyl amino phenoxy) naphthalene using diamino diphenyl sulfone (DDS), diamino diphenyl methane (DDM), triethylene tetra amine (TETA) and diethylene triamine (DETA) as curing agents were studied kinetically by differential scanning calorimetry. The dynamic scans in the temperature range (20–300°C) were analyzed to estimate the activation energy and the order of reaction for the curing process using some empirical relations. The ...

The dynamics of diglycidyl ether of bisphenol-A (DGEBA) was studied by employing broadband dielectric spectroscopy over a wide temperature range extending from below to above the glass-transition temperature. Dielectric spectra reveal the existence of two relaxation processes: the structural relaxation, slowing down for decreasing temperature and freezing at {T}_{g} and a secondary process present in both liquid and glassy phase. Above the glass transition the temperature behavior of the stru...

Siloxane-incorporated epoxy (ESDG) copolymers were prepared by a hot-melt method. IR, 1H- and 13C-NMR are used to determine the structures. The data on the molecular properties indicate that reaction proceeded with a random polycondensation without involving the opening of the oxirane ring in the epoxy structure. Lowering Tgs with increasing siloxane content in copolymers are observed except for the copolymer modified with PDMS siloxane oligomer. Thermal stability data indicate that siloxane moi...

Siloxane-modified sulfone-containing epoxy resins (ESBS) were prepared by polycondensation of PMPS and/or PDMS siloxane oligomers with EBS, the sulfone-containing epoxy resin. Structures were analyzed by IR, 1 H-, and 13 C-NMR. The siloxane content in the copolymers was determined by 1 H-NMR with an integration technique. Epoxy equivalent weight (EEW) determination indicated that the oxirane ring of EBS was intact with this hot-melt procedure. The GPC measurement of these ESBS copolymers showed ...

Cross-linked composites were synthesized via internal compounding of Polydimethylsiloxane and Polytetraflouroethylene micro-powder (PTFEMP) in various proportions and subsequently cross-linking to different extent by electron beam irradiation. The PTFE micro-powder was generated by degrading PTFE ribbons using gamma radiation in presence of CCl4. Elastic modulus of the composites increasedwith radiation doseupto300kGy. Thecomposi-tes showed greater increase in elastic modulus than pure PDMS. Pol...
