摘要： This disclosure relates to functionalized polymers and compositions comprising such where the functionalized polymers comprise amide, imide, and/or ester functionalized partially or fully saturated polymer comprising C4-5 olefins having: i) an Mw/Mn of less than 2, ii) a Functionality Distribution (Fd) value of 3.5 or less, and iii) an Mn of 10,000 g/mol or more (GPC-PS) of the polymer prior to functionalization, provided that, if the polymer prior to functionalization is a copolymer of isoprene and butadiene, then the Mn of the copolymer is greater than 25,000 g/mol (GPC-PS).

摘要： A conjugated diene-based polymer has a value α defined by mathematical expression (i) of 0.65 to 0.97. p, q, r, and s represent compositional ratios (mole ratios) of the structural units represented by formulas (1) to (4) respectively in the polymer. The conjugated diene-based polymer includes, in an amount of 25 to 75 mass%, polymer (A1) which has a multi-branched structure having 4 or more molecular chains. The polymer (A1) has a functional group containing at least one element selected from the group consisting of nitrogen, oxygen, and sulfur at one or both of a terminal and a branching point of the polymer (A1). α = p + 0.5 × r / p + q + 0.5 × r + s
