  5    一个典型示例

   A detailed study of the melting behavior of oriented isotactic polypropylene has been carried out using differential scanning calorimetry.   The orientation in isotactic polypropylene was produced by extruding it in solid phase.   At extrusion ratio (ER ) greater four, two melting peaks were observed. With increasing ER, the lower temperature peak was found to shift to higher temperature. The corresponding shift in the higher temperature peak was much less.   It is shown that these peaks originate in the melting of crystalline species having different degrees of crystal disorder and stereo-block character.
