日本工业技术院纤维高分子材料研究所井口正俊等对多种聚合体系,进行了聚合条件与所获聚合物结构间关系的系统研究,终于在世界上首次制备出聚合物须晶(Polymer whisker),并研究了这种聚合物单晶特有的热、机械、界面等性质以及热发光性。井口等用BF_3/H_2O为催化剂,在非极性溶剂三氧杂环己烷(Trioxane)中进行阳离子聚合,得到了聚甲醛(POM,Polyoxymethylene)的针状单晶。结晶从许多中心放射状生长,粗1—3μm,长可达0.1mm,可以一根根分开。通过光学显微镜、电子显微镜、X射线衍射
Japan Institute of Technology, Institute of Fiber Polymer Materials, Masayuki Iguchi and many other polymerization systems, polymerization conditions and polymer structure obtained by the relationship between the system, and finally for the first time in the world to prepare polymer whiskers (Polymer whisker) , And studied the unique thermal, mechanical, interface and other properties of the polymer single crystal as well as the luminescence. Wellhead and other BF_3 / H_2O as a catalyst in the non-polar solvent trioxane for cationic polymerization, to obtain a POM (polyoxymethylene) needle-like single crystal. Crystals grow radially from many centers, roughly 1-3 μm in diameter, up to 0.1 mm in length, separated by one root. By light microscopy, electron microscopy, X-ray diffraction
