Title:
MEMBER FOR A FOOTWEAR
Document Type and Number:
Japanese Patent JP3260042
Kind Code:
B2
Abstract:
PURPOSE: To provide a member for a footwear with excellent shock absorption properties by using a high polymer composition with specific physical properties, which contains a low molecular weight material holding composite comprising a low molecular material and a medium, and a high molecular weight material.
CONSTITUTION: This member for a footwear employs a high molecular weight composition with specific physical properties, which contains a low molecular weight material holding composite comprising a low molecular material and a medium, and a high molecular weight material as constituting materials. The low molecular weight material contained in the polymer composition has viscosity of 5×105cps or lower at 100°C, and the difference between solubility parameter of the low molecular weight material and that of the medium is 3.0 or lower. The weight ratio of the low molecular weight material to the medium in the polymer composition is 1.0 or higher, and the difference between solubility parameter of the low molecular weight material and that of the polymer material is 4.0 or lower. The weight ratio of the low molecular weight material to the high molecular weight material in the polymer composition is 0.5 or higher. This high polymer composition 5, for example, is used for the tread part of an insole 2 of a shoe 1.
