Abstract:

A novel approach was presented on lowering the high processing viscosity of poly(ether ether ketone)s(PEEK). The commercial PEEK and poly(ether ether ether ketone)s-poly(ether ketone)s(PEEEK-PEK) were synthesized via a typical procedure. Compared to PEEK, PEEEK-PEK had the same molar ratio of ether and ketone linkages but in different linkage sequencing. Results of the DSC, DMA, TGA and Stress-strain tests indicated that the two copolymers performed close thermal and mechanical properties. Moreover, the rheological behavior was particularly investigated and it occurred that the melt viscosity of PEEEK-PEK exhibited around 50% lower than that of PEEK according to the dynamic shear rheological tests at the rate of 100 rad/s.

Key words: High performance polymer, Melt viscosity, Poly(ether ether ketone)
