发明名称 Conjugated diene polymer, method for producing conjugated diene polymer, and conjugated diene polymer composition
摘要 A conjugated diene polymer is provided that contains a conjugated diene-based monomer unit and a group represented by Formula (I) below, at least peaks H, M, and L below being present in a molecular weight distribution curve obtained by gel permeation chromatography measurement, and when the total area of the molecular weight distribution curve is 100%, the total peak area of peak H is 3% to 30%, the total peak area of peak M is 5% to 45%, and the total peak area of peak L is 40% to 80% (in Formula (I), R1 and R2 independently denote a hydrocarbon group having 1 to 4 carbon atoms, a hydrocarbonoxy group having 1 to 4 carbon atoms, a hydroxy group, or a polymer chain containing a conjugated diene-based monomer unit, m denotes an integer of 0 to 10, and A1 denotes a polar functional group that does not have an active hydrogen) Peak H: a peak for which the molecular weight at the peak top is higher than the molecular weight at the peak top of peak M Peak M: a peak for which, when the molecular weight at the peak top of peak H is MH, the molecular weight at the peak top is 0.6×MH to 0.8×MH Peak L: a peak for which, when the molecular weight at the peak top of peak H is MH, the molecular weight at the peak top is 0.2×MH to 0.4×MH.
