New Reactive Compatibilizer B Preparation and its Application in Polystyrene Ether/Nylon 66 Alloy

Abstract:

A new type compatibilizer-boric acid ester with carboxylic acid functional groups (refered as B) was synthesized and used in PPO/PA66 alloys. The PPO/PA66 alloys were produced by melting blending. 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) and mechanical test. The effects of the compatibilizer B on the mechanical property and morphology of PPO/PA alloy were discussed. The results showed that, the compatibilizer B can also improve the mechanical property, besides showing good effect on the compatibility improvement for PPO/PA blends; it (B) acts as a compatibilizer for the blends by forming interim layer with dispersed phase PPO and continuous phase PA. The compatibilization of PPO and PA66 alloy was due to the chemical reaction between carboxyl group and amine group.
