Title:
【発明の名称】超延伸可能な重合体材料の製法、超延伸可能な材料及び該材料を用いた物品の製法
Document Type and Number:
Japanese Patent JP2740187
Kind Code:
B2
Abstract:
An ultrastretchable polymer material is prepared starting from polyolefine particles with a low entanglement density and a weight average molecular weight (MW) higher than 400,000, the particles being densified to a coherent material together with a process auxiliary material at an elevated temperature, but below the melting point of the pure polyolefine. From this ultrastretchable material, objects with a high tensile strength and a high modulus can be produced by stretching it, for instance, at a temperature which is at most 70 DEG C below the temperature at which the polyolefine melts under the prevailing conditions, if desired after removal of the process auxiliary agent present in it.
