Abstract
A low viscosity tetrafunctional epoxy resin was synthesized by reactin g amino-terminated polydimethylsiloxane with epichlorohydrin followed by dehydrohalogenation. The synthesized tetrafunctional aliphatic epox y resin had an epoxy equivalent weight of 382, M-n of 1492, M-w of 229 6, and a viscosity of 4.2 poise at 25 degrees C. The chemical structur e of the tetrafunctional aliphatic epoxy resin was studied by gel perm eation chromatography (GPC), Fourier transform infrared spectra (FTIR) , and H-1-NMR spectra. Results showed the tetrafunctional aliphatic ep oxy-blended aromatic epoxy resin possessed high impact strength and fl exural strength. SEM photographs were investigated to study the compat ibility of the blended epoxy system. (C) 1998 John Wiley & Sons, Inc.
