| 英文摘要 | Syndiotactic polypropylene ( sPP) fibers with different initial structures were prepared by melt-spinning and subsequent heat treatment. Structure transition and melting behavior during the heating process were, systematically investigated by a combination of differential scanning calorimetry (DSC) and temperature variable wide angle X-ray diffraction (WAXD) The results indicate that the melting peak at temperatures lower than 100 degrees C is attributed to the melting or transition of mesophase. With increasing temperature, the crystals form I and form II in as-spun and annealed fibers melt directly, indicating that no occurrence of the transition from form 11 to form I. For sPP fibers with mesophase,partial mesophase can transform directly to form 11 and some mesophase melts and forms crystal form I in the following heating process. For annealed sPP fibers with crystals form I and U ( sPP-300-1.5-80), the highest-temperature melting peak (T(m.3)) is mainly attributed to the melting of crystal form I produced during the course of melt recrystallization at T(m.2). Structure transition and multiple melting peaks of the sPP fiber,, during heating process are determined by the initial structure and the preparation conditions of the fibers. |
