The solid state film extrusion of poly (1-butene) was carried out under 2500 atm at 100°C. Extrudates with smooth surfaces were not produced from unoriented pristine samples but successfully obtained by using the preoriented sample (draw ratio=1.5) as a starting material and by pulling the film extruded at the exit of high pressure die. Films thus obtained were flexible and transparent. X-ray diffraction studies of the extrudates have been made to determine the selective orientation of form I crystals. The extruded films show the double orientation with the c-axis preferentially oriented to the machine direction and with the a-axis parallel to the film surface. This selective orientation was explained by assuming that the (300) plane of a form I crystal preferentially glides upon the extrusion.
