<p><P>PROBLEM TO BE SOLVED: To provide a 4-methyl-1-pentene polymer film which is excellent in biaxial orientation moldability. <P>SOLUTION: In a method for producing the 4-methyl-1-pentene polymer film for biaxial orientation in which after the 4-methyl-1-pentene polymer is melt-extruded in the shape of a film from a die, the filmy 4-methyl-1-pentene polymer is passed between paired rolls to produce the 4-methyl-1-pentene polymer film, a roll line pressure to the filmy melt-extruded polymer passing between the rolls is made to be 0.1-90 kg/cm. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
