Amino Terminated Unsaturated Polyamides and Their Application as Epoxy Resin Hardener
نویسنده
چکیده
Polymerization of β-phenyl glutaconic diethyl ester (GE) with various diamines (DA) at 1:2 molar ratios in 1,4dioxane solvent was carried out at reflux temperature. The resultant amino terminated unsaturated oligomers (ATUP) were characterized by elemental analysis, number of terminal amino groups, IR spectral studies, number average molecular weight estimated by non-aqueous conductometric titration and thrmogravimetry. These ATUP oligomers were used to cure epoxy resin, namely diglycidyl ether of bisphenol-A, and studied by differential scanning calorimetry (DSC). The unreinforced ATUP products have also been prepared and characterized. Glass reinforced composites based on the ATUP epoxy system have also been prepared and characterized.

Occupational Allergic Dermatitis Induced by an Epoxy Hardener Alkylamine
Epoxy resins have been widely used in commercial applications, and their adverse health effects have been mostly reported in occupational settings. The most frequent adverse effects are irritation or allergic mechanisms involving the dermal and respiratory systems. Sensitization is usually caused by low molecular weight or short-chain compounds. We report here two workers exposed to an epoxy re...

Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a coupling agent. To increase the compatibility between the epoxy resin and HTPB part, polar groups were introduced in the later to achieve physical and chemical interactions between...

First shell substitution effects were incorporated into a kinetic reaction model descriptive of the polymerization of an epoxy resin formulated from diglycidyl ether of bisphenol A and 4,4'diaminodiphenylmethane. Analysis of populaiion density distribution dynamics for the hardener and several oligomers in the sol fraction showed that the reactivity of secondary amino hydrogens is less than the...

Hydroxyl terminated polybutadien that is known as HTPB resin is a liquid hydrocarbon polyol that is commonly used in preparation of solid composite propellants. Because of unsaturated nature of repeating unit of HTPB polymer , it has high potential for oxidative aging . In this paper ,we have investigated aging behaviors of two types of HTPB which having various content of phenolic antioxida...
متن کاملImpact Resistance Enhancement by Adding Core-Shell Particle to Epoxy Resin Modified with Hyperbranched Polymer
A core-shell particle was fabricated by grafting amino-terminated hyperbranched polymer to the surface of silica nanoparticles. The influences of core-shell particle contents on the tensile and impact strength of the epoxy thermosets modified with amino-terminated hyperbranched polymer were discussed in detail. For comparison, core-shell particle was added into the epoxy/polyamide system for to...
