 note = {The thermally and mechanical deformation induced solid-state phase transition of polyoxymethylene from the orthorhombic (metastable phase) to the trigonal phase (stable phase) has been investigated by means of DSC, IR and Raman spectroscopic methods, using two single crystals (moth-shaped and rod-like crystals) of orthorhombic polyoxymethylene differed in an observation by a light microscope. Upon being heated, drawn and ground, the metastable orthorhombic crystals transform irreversibly to the stable trigonal form of polyoxymethylene. In the before and after this solidstate phase transition, the molphology, the fiber axis orientation, and the extendedchain structure of the starting orthorhombic single crystals were kept unaltered. It was clear this transitional behavior was of the change from single crystal to single crystal between the modifications of polyoxymethylene. And it is presumed that both orthorhombic polyoxymethylene single crystals of the starting materials consist of the extended chains., 長崎大学教育学部自然科学研究報告. vol.41, p.1-11; 1989},
