| Abstract: | A new approach for enhancing the compatibility of liquid crystalline polymers (LCPs) with engineering thermoplastics is developed in this paper. By adding a new type of compatibilizer to poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO)/LCP blends (semi‐interpenetrating LCP network (ILCPN) comprising the liquid crystalline polymer poly‐(ethylene terephthalate)/p‐hydroxybenzoic acid (PET/60PHB) and crosslinked polystyrene), a well‐compatibilized PPO/LCP composite with considerably improved mechanical properties was obtained. Compared with the uncompatibilized PPO/LCP blend, the bending strength and the Izod impact strength of the compatibilized sample with 5% semi‐ILCPN increase more than 2 and 4 times, respectively. |
