Document Type and Number:
Japanese Patent JP6673704
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic polymer composition for damping material capable of enhancing tanδ at 23°C.SOLUTION: The thermoplastic polymer composition for damping material contains a 4-methyl-1-pentene α-olefin copolymer (A) containing a constitutional unit (A-i) derived from 4-methyl-1-pentene and a constitutional unit (A-ii) derived from other α-olefin with the constitutional unit (A-i) of 63 to 86 mol% and the constitutional unit (A-ii) of 14 to 37 mol% and a thermoplastic elastomer composition (B) obtained by dynamically crosslinking a mixture containing a copolymer [B-I] containing a constitutional unit (B-i) derived from ethylene, a constitutional unit (B-ii) derived from other α-olefin and a constitutional unit (B-iii) derived from non-conjugated polyene and a polyolefin resin [B-II] and has mass ratio of the copolymer (A) and the composition (B), (A)/(B), of 10/90 to 49/51.SELECTED DRAWING: None
