The Study on the Preparation and Properties of PPO/PA66 Alloy with A New Type of Compatibtlizer B

摘要

By blending homemade compatibilizer with carboxylic acid functional groups into the basic materials of PPO and PA66, through twin-screw extruder blending, the PPO/PA66 alloy was prepared. The micromorphological and mechanical properties of PPO/PA66 blends with different contents of the compatibilizer were studied by transmission electron microscope (TEM), scanning electron microscope (SEM) , mechanical test and Molau test. The results showed that the homemade compatibilizer can improve the mechanical property. Besides showing good effect on the compatibility improvement for PPO/PA blends, it has an in-situ compatibilization for the PPO/PA66 alloy.
