The topological system has excellent compatibility with rubber components used for tires and other rubber products, has rubber properties without fluidization in the temperature range when the tires are used, and has low energy loss. Provided are an elastic polymer composition having bonding-specific characteristics, and a pneumatic tire containing the same. An elastic polymer composition comprising a polycatenan structure having a sulfur atom, wherein the polycatenan structure has a structure in which the polycatenan structures are bonded together by chemical crosslinking or ionic crosslinking, and air containing the same. Enter tire. [Selection figure] None |
