SHEET-FORMED MATERIAL
Document Type and Number:
Japanese Patent JP3310410
Kind Code:
B2
Abstract:
PURPOSE: To provide a flexible sheet-formed material having excellent solvent resistance and good low-temperature characteristics and mechanical strengths.
CONSTITUTION: This sheet-formed material is composed of a hydrogenated block copolymer having an average molecular weight of 18,000-800,000 and having a structure expressed by the general formula Z-X-Y-X-Z (X is polymer block composed of a vinyl aromatic compound; Y is polymer block composed of a conjugated diene; Z is polymer block composed of butadiene and having an average molecular weight of 1,500-50,000), wherein the 1,4-bond content in the block chain expressed by Z is ≥70% and ≥80% of the unsaturated bond in the block chains of Y and Z is hydrogenated.
