摘要: A polybutadiene in which the values of e, f, and g calculated from following determinant (I): (I) [wherein symbol a is peak value at around 1,130 cm-1 transmittance spectrum obtained by Fourier transfer-infrared spectroscopy, b trough 967 spectrum, c 911 d 736 spectrum] satisfy relationship (II): (calculated cis-1,4 bond amount) = e/(e+f+g)x100 ≥ 99 (III): vinyl g/(e+f+g)x100 ≤ 0. With polybutadiene, rubber composition tire can be improved wearing resistance unsusceptibility to crack growth.
