Abstract
A rubber composition including a copolymer represented by general formula (1) and a filler, wherein R1 to R4 each independently represent a hydrogen atom, a halogen atom, an optionally substituted hydrocarbon group having 1 to 20 carbon atoms, or a substituent containing a silicon atom, an oxygen atom, or a nitrogen atom, “x” is 0 to 2, R5 represents a hydrogen atom or a methyl group, “p” is 30 to 2000, and “n” is 200 to 5000; R1 and R2, and R3 and R4 may each be bonded together to form a ring; and multiple R1s to R5s may be the same or different from each other, and the values of a plurality of “x” may be the same or different.
