Description of the Invention: [Technical Field of the Invention] The molding of the polymer composition and the formation of the polymer composition [Prior Art] ^The moldings of various shapes can be obtained at relatively low cost, The polymer composition of a raw compound (such as an insecticide) has been known to the public as a molded article of the "5 composition" and has been widely used in various fields. These moldings are used in the following two ways: the evapotranspiration of the compound Or bleed the active compound: read the release of the compound, that is, so-called bleedlng (see Patent Document 1). It is difficult to have a compound! When the evapotranspiration property is low, the compound is released from the sputum by exudation. 'Therefore, the amount of the main compound of this compound exceeds "=°° release. When the activity remaining in the molded product produces a saturation amount of μ,8 (which is a supersaturation amount), the active compound which is supersaturated (=live, to the surface J of the molded article) The amount of saturation) is a phenomenon that migrates with time. When the molded article is formed by a composition containing a compound (tetra) which is more than saturated, the active compound has a tendency to decrease with the initial addition amount of the active compound ==. On the other hand, when the infiltration of the compound on the molded article is present, there is an indication that the 321695 3 201121417 interval will become the effective period of the molded article. Therefore, once the expiration date of the molded article is determined, the initial addition amount of the releasable active compound is inevitably determined. In order to obtain a molded article which can be used for a long period of time, it is necessary to use a polymer composition containing an amount of the active compound in excess of the amount of the polymer saturated. However, a molded article formed by a polymer composition containing a supersaturated amount of the active compound in the polymer exudes a large amount of the active compound in the early stage of its use, so that the bleeding rate cannot be maintained for a desired period of time. Patent Document 1: JP-A-6-315332 [Disclosed from the results of intensive studies by the inventors, it has been found that an olefin-based polymer composition containing an olefin-based polymer, an active compound, and a Cmo saturated chain hydrocarbon and/or liquid paraffin is found. Stretching the formed molded article at a stretching ratio of 2 or more can prevent a decrease in the bleeding rate of the active compound, and thus it becomes possible to increase the amount of exudation of the active compound over a specific period of time. The present invention has been completed based on this finding. That is, the present invention provides a molded article formed of a polymer composition comprising: 100 parts by weight of an olefin-based polymer; and 0 to 100 parts by weight of the olefin-based polymer. 01 to 100 parts by weight of C. , a saturated chain hydrocarbon and/or a liquid paraffin; and 0 to 100 parts by weight of the olefin polymer. 01 to 200 parts by weight of the releasable active compound, and the polymer composition is stretched at a stretching ratio of 2 or more. According to the present invention, since the rate of exudation of the active compound can be inhibited, it is possible to provide a method for improving the active compound within a predetermined period of time, as well as a method for producing the molded article, as described in 4,321,695, 2011,214,17. . [Embodiment] The present invention provides a molded article formed of a polymer composition comprising: (10) parts by weight of a chiral polymer, and a hydrocarbon polymer per (10) parts by weight g.

Q1 to 2GG parts by weight of releasable living person' and the polymer composition is σ at a stretching ratio of 2 or more.
