摘要：

Binary blends of polypropylene with a linear low density polyethylene were prepared in solution, dried and studied by transmission electron microscopy using surface replicas of samples prepared by remelting and quenching. Very clear micrographs were obtained with a wealth of morphological detail. Phase separation was observed over a wide composition range for blends quenched from 190-degrees-C. A few samples were prepared by melt mixing in a twin-screw extruder; others, containing deuterated polypropylene, were prepared by solution blending. These special blends showed the same morphologies as normal blends prepared in solution to the same composition.
