Abstract: The present disclosure provides a method for recovering bitumen that includes contacting bitumen with steam and/or water and an organic amine having a boiling point at one atmosphere of greater than 145 o C and recovering the bitumen. The bitumen can in oil sands, where the step of contacting includes contacting the oil sands having bitumen with the steam and/or water and the organic amine. Contacting the bitumen with the steam and/or water and the organic amine and recovering the bitumen can be done in-situ in a subterranean formation.

Abstract: A process to form a composition comprising an ethylene/vinylarene diblock and/or triblock interpolymer, and comprising at least the following steps: A) polymerizing in a reactor A, a mixture A comprising ethylene, and optionally an alpha-olefin, and optionally a vinylarene, in the presence of at least the following: a) a metal complex S selected from the following: Formula (S1), Formula (S2), Formula (S3), Formula (S4) or Formula (S5), as described herein: B) polymerizing in a reactor B, a mixture B comprising ethylene, a vinylarene, and optionally an alpha-olefin, in the presence of at least the following: b) a metal complex H selected from the following Formula (H1) or Formula (H2), as described herein; and wherein step A occurs before step B, or vise-versa, and at least one chain shuttling agent is fed into the first reactor. A composition comprising an ethylene/vinylarene diblock or triblock interpolymer, as described herein.
