Chemiluminescence of epoxy resin
Polymer Degradation and Stability, 2002It was found that chemiluminescence (CL) of epoxy resin proceeds by a two step process. The first step is the formation of a substance causing CL and the second step is its reaction producing luminescence emission. The first step is predominant at room temperature, so that the CL-causing substance accumulates when a specimen is left in ambient ...

Bisphenol-A epoxy resin reinforced and toughened by hyperbranched epoxy resin
Frontiers of Chemical Engineering in China, 2007The study on toughening and reinforcing of bisphenol-A epoxy resin is one of important developmental direction in the field. This paper reports a one-pot synthesis of aromatic polyester hyperbranched epoxy resin HTDE-2, an effect of HTDE-2 content on the mechanical and thermal performance of the bisphenol-A (E51)/HTDE-2 hybrid resin in detail.

High-Performing and Fire-Resistant Biobased Epoxy Resin from Renewable Sources
, 2018Epoxy resins with high thermal and mechanical performance as well as good resistance to fire are difficult to synthesize. In this work, a high-performance intrinsically flame-retardant epoxy resin (diglycidyl ether of daidzein (DGED)) was synthesized ...

Publisher Summary Epoxy resins are formed from an oligomer containing at least two epoxide groups and a curing agent, usually either an amine compound or a diacid compound. Epichlorohydrin is the monomer used for the synthesis of glycidyl ethers and glycidyl esters.

AbstractTransparent, X‐ray contrast (radiopaque) epoxy resins were obtained by dissolving up to 25 wt % triphenylbismuth in the commercial epoxy resin prepolymers EPON‐815, DER‐330, DER‐383, and DEN‐431 which were then hardened with diethylenetriamine.

Publisher Summary This chapter focuses on a study that was conducted to test for bond strength on a representative matrix of commonly used plastics and the adhesives best suited to them. The study concentrates on epoxy resin. The block-shear (ASTM D 4501) test was chosen as the test method because it places the load on a thicker section of the test ...

AbstractThe curing behavior of epoxy resins prepared by reacting epichlorohydrin with 4,4′‐diaminodiphenyl methane (DADPM)/4,4′‐diaminodiphenyl ether (DADPE) or 4,4′‐diaminodiphenyl sulfone (DDS) was investigated using DDS and tris‐(m‐aminophenyl)phosphine oxide (TAP) as curing agents.
