<P>PROBLEM TO BE SOLVED: To provide a molded body containing a 4-methyl-1-pentene-based polymer that avoids discoloration and crack generation and can withstand longer-term use. <P>SOLUTION: A 4-methyl-1-pentene-based polymer composition is produced by blending 100 pts.wt. of a 4-methyl-1-pentene-based polymer (A) with 0.01-1.5 pt.wt. of a benzotriazole-based ultraviolet absorber (B) and 0.03-4.5 pts.wt. of a hindered amine-based light stabilizer (C) in a weight ratio (B):(C) of (1:2) to (1:4.5). <P>COPYRIGHT: (C)2012,JPO&INPIT |
