Notes:
Glycidol has been introduced into isocyanate-terminated polyurethane to form glycidyl-terminated polyurethane resin. A series of glycidyl-terminated polyurethanes, based on PTMEG, PPG, and polyester soft segments, having different molecular weights were synthesized and their adhesion properties on aluminum were evaluated. The effect of the soft-segment structure, soft-segment length, and temperature on adhesion were examined. It was found that the resin showed superior adhesion at cryogenic temperatures. The results coincide with the phenomenon observed in dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM). In addition, the modified system also offered some distinct advantages over the commercial polyurethane adhesives, e.g., good storage stability and room-temperature curing. © 1994 John Wiley & Sons, Inc.
