Morphology and property relationships in ternary blends of polyethylene/polyamide‐6/compatibilizing agents

Abstract

AbstractThe effects of compatibilizing agents on the morphology and properties of high density polyethylene (HDPE) and polyamide‐6 blends were investigated. The ternary blends were studied with the objective of understanding and optimizing the compatibilization of HDPE and polyamide‐6. The blends were prepared by melt mixing the individual components in a twin‐screw extruder. Mechanical property, rheological property, differential scanning calorimetry, and scanning electron microscopy results are discussed. The addition of compatibilizing agents results in a greatly reduced dispersed phase particle size. The properties of the blends level out after a compatibilizer level of 3 wt% has been reached. The rheological, mechanical, and thermal property results indicate the presence of the compatibilizing agent along the interfacial boundary regions between the other two phases. © 1995 John Wiley & Sons, Inc.
