Summary

The structures and thermal and mechanical properties of poly(phenylene oxide) (PPO) blends with high impact polystyrene (HIPS) were investigated. Two types of PPO were used: commercial one and the other prepared in Industrial Chemistry Research Institute (ICRI) in large laboratory scale process of oxidative polycondensation of 2,6-dimethylphenol, in the presence of complex of copper(II) bromide with morpholine as acatalyst (PPO-IChP). It has been proved that PPO/HIPS blends are miscible in amorphic state, independently on PPO type, because they show the single glass transition temperature, determined by differential scanning calorimetry (DSC) and dynamic­ mechanical thermal analysis (DMTA). Homogeneity of the blends was confirmed by scanning electron microscope (SEM) method. The PPO-IChP/HIPS blend showed significantly higher impact strength and relative elongation at break than PPO-h/HIPS one. The type of PPO used did not influence alot heat distortion heat deflection temperature (HDT) as well as tensile or flexural strength of the blends investigated. PPO-IChP and PPO-IChP/HIPS blend showed aslightly better thermal stability than PPO-h and PPO-h/HIPS blend.
