✦ Synopsis

A static mixer assembled on a Brabender plastograph has been used as a blender of immiscible polymers like low-density polyethylene (LDPE ) and polyamide 6 (PA6 ). The shearing rates were 50 and 100 s 01 . The properties of polymer blends were tested using a thermomechanical method. It was found that a tested prototype static mixer imparted good uniformity to the blends' structure on a level similar to molecular distribution of components. This phenomenon is called mechanical compatibilization. High effectiveness of mixing was observed for LDPE -PA6 compositions with and without a compatibilizer.
