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

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
