| 中文摘要 | the crystallization and melting behaviours of a multiblock copolymer comprising poly(ether ether ketone) (peek) and poly(ether sulfone) (pes) blocks whose number average molecular weights <((m)over bar (n)'s)> were 10 000 and 2900, respectively, were studied. the effect of thermal history on crystallization was investigated by wide-angle x-ray diffraction measurement. a differential scanning calorimeter was used to detect the thermal transitions and to monitor the energy evolved during the isothermal crystallization process from the melt. the results suggest that the crystallization of the copolymer becomes more difficult as compared with that of pure peek. the equilibrium melting point of the copolymer was found to be 357 degrees c, about 30 degrees c lower than that of pure peek. during the isothermal crystallization, relative crystallinity increased with crystallization time, following an avrami equation with exponent n approximate to 2. the fold surface free energy for the copolymer crystallized from the melt was calculated to be 73 erg cm(-2), about 24 erg cm(-2) higher than that of pure peek. copyright (c) 1996 elsevier science ltd. |
