摘要： A VM concentrate comprising: from about 60 to about 95 parts (and at least 50 wt %) of a diluent oil (e.g., having a KV100 of about 2 cSt to about 40 cSt); and from about 5 parts to about 40 parts (and at least 6.0 wt %) of a linear triblock copolymer characterized by the formula: D′-PA-D″; wherein D′ represents a block derived from diene, PA represents a block derived from monoalkenyl arene, D″ represents a block derived from diene, and the linear triblock copolymer is present in an amount effective to modify a lubricating kinematic viscosity at approximately 100° C. (KV100) of the concentrate, and wherein the KV100 of the concentrate is about 3000 cSt or less. The linear triblock copolymer may additionally or alternatively have a thickening efficiency span of at most 0.5.

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).
