    • PROBLEM TO BE SOLVED: To produce a 4-methyl-1-pentene polymer excellent in stereoregularity, transparency and heat resistance, and a film excellent in transparency, heat resistance, releasability and suitable as a release film, which is obtained from the 4-methyl-1-pentene polymer.SOLUTION: The 4-methyl-1-pentene copolymer includes a structural unit derived from 4-methyl-1-pentene by 80 to 99.9 mass% and a structural unit derived from at least one α-olefin having 3 to 11 carbon atoms, excluding 4-methyl-1-pentene, by 0.1 to 20 mass%, in which a ratio (a/b) of the content amass% of structural units derived from the α-olefin having 3 to 11 carbon atoms excluding 4-methyl-1-pentene in a n-decane soluble component to the content bmass% of structural units derived from the at least one α-olefin having 3 to 11 carbon atoms excluding 4-methyl-1-pentene in the copolymer ranges from 2.0 to 4.0. A film is produced from the 4-methyl-1-pentene polymer.
    • 要解决的问题:为了制备立构规整性,透明性和耐热性优异的4-甲基-1-戊烯聚合物,以及透明性,耐热性,脱模性优异且适合作为脱模膜的膜,其由4- 甲基-1-戊烯聚合物。溶液:4-甲基-1-戊烯共聚物包括衍生自80-99.9质量%的4-甲基-1-戊烯的结构单元和衍生自至少一种α-烯烃的结构单元,其具有 3〜11个碳原子(不包括4-甲基-1-戊烯)0.1〜20质量%,其中来自具有3〜11个碳原子的α-烯烃的结构单元的含量的氨基酸的比例(a / b) 在正癸烷可溶成分中除去4-甲基-1-戊烯以外的原子的至少1种以上的除了4-甲基-1-戊烯以外的含有3〜11个碳原子的α-烯烃的结构单元的含量bmass% 范围从2.0到4.0。 由4-甲基-1-戊烯聚合物制备薄膜。
