Preparation and Characterization of Polyoxymethlene/Thermoplastic Polyamide Elastomer Blends Compatibilized by Maleic Anhydride Grafted ABS Copolymer

Polyoxymethylene/thermoplastic polyamide elastomer composites were prepared by using maleic anhydride grafted acrylonitrile-butadiene-styrene copolymer as interfacial compatibilizer via melt extrusion. The compatibility and the properties of blends were studied by the mechanical testing and various physical chemical methods. The notched impact strength and elongation at break of blends were increased significantly after adding of compatibilizer. Simultaneously, the phase structure and crystal shape of the blends were changed. Finally, the elastomer particles were more uniform, and more amorphous regions were produced in the blends.
