Notes:
A series of small-angle X-ray scattering measurements were performed to study the polypropylene/nylon-6,6 polymer blends with or without the compatibilizer: maleated polypropylene. The blends were made at various temperatures using a venting conical twin-screw extruder with a constant extruding flow rate. The X-ray scattering results show that the dispersion of nylon-6,6 in polypropylene is improved for temperature above the melting point of nylon-6,6 (265°C) when the compatibilizer involved is not used. As the compatibilizer is incorporated, the dispersion is significantly improved, even at the temperature below 265°C. With the compatibilizer, the dispersed nylon-6,6 particle size and shape in the blends are independent of blending temperature, suggesting that the temperature effect is overwhelmed by the effect of the compatibilizer. © 1995 John Wiley & Sons, Inc.
