返すことが可能である。In the present invention, 1-113Off11 of polycaprolactone resin is added to 1.00 parts by weight of polyolefin resin.
It has been discovered that by blending the polyolefin resin with a certain amount, shape-memory functions that are not possessed by the polyolefin resin alone can be expressed, and molded products made using the blended composition exhibit a shape-memory function that is not possessed by the polyolefin resin alone. Shape memory, that is, determination of a predetermined shape (hereinafter referred to as primary shape) is possible at a temperature equal to or higher than the melting point, and the determination of this primary shape can be repeated any number of times.
この点は、架橋が不可欠であり一度しか１次形状決定が
できない前述の従来技術にない特徴を有している。This point has a feature not found in the above-mentioned prior art, in which crosslinking is essential and the primary shape can only be determined once.
