Abstract:
1. A film obtained by forming a copolymer containing 92 to 98 mass % of structural units derived from 4-methyl-1-pentene and 2 to 8 mass % of structural units derived from at least one selected from the group consisting of 1-dodecene, 1-tetradecene, 1-hexadecene and 1-octadecene, wherein the ratio c 2 /d 2 is in the range of 0.1 to 1.5, wherein c 2 represents the blocking factor in g/cm of the film, and d 2 represents the content in mol % of structural units derived from the at least one selected from the group consisting of 1-dodecene, 1-tetradecene, 1-hexadecene and 1-octadecene in the n-decane-soluble component of the copolymer.
