Title:
POLYMER COMPOSITION, CROSSLINKED POLYMER, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2021/256419
Kind Code:
A1
Abstract:
Provided is a polymer composition that has excellent processability and that is suitable for manufacturing a tire having a high level of superior balance in terms of low fuel consumption, wet-gripping ability, tensile strength, and ozone resistance. The polymer composition according to the present invention contains: (A) a modified conjugated-diene based polymer which is a copolymer of an aromatic vinyl compound and a conjugated-diene compound or a polymer of the conjugated-diene compound, and which is a reaction product between an active polymerization terminal and a compound represented by any one of general formulae (1)-(4); (B) a first surfactant which is an ester of a first fatty acid and a first polyhydric alcohol having a structure in which carbon atoms each bound to a hydroxyl group are not located adjacent to each other; and (C) a second surfactant which is an ester of a second fatty acid and a second polyhydric alcohol having a structure in which carbon atoms each bound to a hydroxyl group are bound to each other.
