Abstract:

To expand applications of poly(phthalazinone ether ketone) (PPEK) in fiber preparation, PPEK fibers were prepared by dry spinning with PPEK and mixed solvent of p-chlorophenol and 1,1',2,2'-tetrachloroethane (volume ratio is 1:1). PPEK solution and PPEK fibers were characterized by rotating rheometer, differential scanning calorimeter, polarizing microscope, universal tensile tester, X-ray diffractometer and fiber sound velocimeter. The results show that optimal spinning temperature of 40% PPEK solution is 140 ℃. After being elongated by 1.43 times, breaking strength, elastic modulus and sonic orientation factor of PPEK fibers reach 167.6 MPa, 4.6 GPa and 0.570 5, respectively. Hot elongated PPEK fibers has good heat resistance and remains amorphous with glass transition temperature of higher than 250 ℃.

Key words: poly(aryl ether ketone), diazanaphthalene, mixed solvent, dry spinning, high temperature resistance performance
