Polybutene molding

Abstract

PURPOSE: To obtain the subject crystalline molding having a specified crystalline structure by molding a polybutene having syndiotactic structure. CONSTITUTION: An objective molding obtained by molding a polybutene (polybutene-1 preferably having ≥0.7 syndiotactic pentad fraction) having substantially syndiotactic structure and having a rhombic system in which a=16.9, b=6.05 and c=7.78Å as the lattice constant determined by X-ray diffraction.
