Abstract

Concentrates of linear, block copolymers having a polymer block derived from a monoalkenyl arene, covalently linked to one or more blocks of a hydrogenated derivative of a conjugated diene copolymer, dissolved in highly saturated diluent oil, wherein the size of the monoalkenyl arene block is controlled to provide an optimized level of incompatibility of the block copolymer in the selected diluent.
