PROBLEM TO BE SOLVED: To provide a polymer composition capable of increasing the amount of an active compound which bleeds in a certain period as compared with conventional ones. SOLUTION: The polymer composition includes 100 pts.wt. of an olefin-based polymer, 0.01-100 pts.wt. of a branched aliphatic acid based on 100 pts.wt. of the olefin-based polymer and 0.01-200 pts.wt. of a releasable active compound. In the polymer composition, the releasable active compound is selected from the group consisting of a pest-controlling agent, a lubricant, an anti-static agent and an anti-fogging agent. In the polymer composition, the olefin-based polymer is an ethylene-α-olefin copolymer having a density of 870-980 kg/m<SP>3</SP>and an MFR of 0.1-20 g/10 min. COPYRIGHT: (C)2011,JPO&INPIT |
