Abstract
In this work, we prepared the interpenetrating polymer networks of bis maleimide and polyether-type polyurethane(polyoxypropylene)-crosslinke d epoxy (BMI/PU(PPG)-EP IPNs) by employing the simultaneous bulk polym erization technique. The polyurethane (PU)-crosslinked epoxy was ident ified via infrared (IR) spectra analysis. Also investigated herein wer e the mechanical properties, including tensile strength, Izod impact s trength, and fracture energy (G(IC)) of the IPNs with various BMI cont ents in PU-crosslinked epoxy matrix. In addition, differential scannin g calorimetry (DSC) analysis and the thermogravimetric analysis (TGA) were performed to examine the thermal properties of the BMI/PU(PPG)-EP IPNs. In addition, morphology and dynamic mechanical analysis (DMA) o f the BMI/PU(PPG)-EP IPNs were also studied. (C) 1998 John Wiley & Son s, Inc.
