Document Type and Number:
WIPO Patent Application WO/2022/138026
Kind Code:
A1
Abstract:
Provided is a polymer composition containing a conjugated diene polymer (A) and an atypical filler (B). The conjugated diene polymer (A) contains a polymer (A1) satisfying the conditions of expression (i) when the structural ratios (molar ratios) in the polymer of the structural unit represented by formula (1), the structural unit represented by formula (2), the structural unit represented by formula (3), and the structural unit represented by formula (4) are p, q, r, and s, respectively. Expression (i): 0.75 ≤ (p + (0.5 × r)) / (p + q + (0.5 × r) + s) ≤ 0.95.
