摘要： 用淬火、熔体拉伸和与其它聚合物共混的方法直接制得了聚偏氟乙烯(PVF2)β相结晶.并深入地研究了淬火、熔体拉伸和共混物组分对PVF2β相结晶的影响.

Abstract: FTIRand TEMhave been used to study the effect of quenching, melt-drawing and blends component on β phase crystallization of PVF2.Low quenching temperature (30℃) induce β phase formation of PVF2 directly from the melt.The melt drawn films of PVF2 consist of highly oriented lamellar structure.Adding a given amount of polymethacrylates (PMAs), especially PMMA, into PVF2 results in formation of fibrillar crystals and β phase.The contents of fibrillar crystals and β phase increases with the increase of the molecular weight of PMAs.
