| Abstract: | Phase behavior in blends of liquid crystalline poly(aryl ether ketone) (C-PAEK) and poly(aryl(ether) ketone) containing 4-methyl phenyl groups(T-PAEK) was investigated by differential scanning calorimetry(DSC),polarized light microscopy(PLM) and atomic force microscopy(AFM) techniques.In both(C-PAEK-rich) and T-PAEK-rich blends,the two components are molecular miscible in the melting state.For the 80/20 C-PAEK/T-PAEK blend,the bright core and rings are mainly composed of C-PAEK phase and dark rings consist of T-PAEK phase in the ring-banded spherulites.The development of the ring-banded spherulites in the C-PAEK/T-PAEK blends is a rhythmic growth process,and thus it is consistent with the structural discontinuity model proposed by Padden and Keith based on polyethylene spherulites. |
