    Abstract: Aspects of the present disclosure relate to Schiff base oligomers and uses thereof. In at least one aspect, an oligomer is represented by Formula (IV) wherein each instance of R9 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl, and ether. Each instance of R28 and R29 of Formula (IV) is independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, and aryl. Each instance of R33 of Formula (IV) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and a bond. Each instance of R41 of Formula (IV) is independently —NH— or a bond and each instance of R40 is independently —NH— or —NH—NH—. Each instance of R42 of Formula (IV) is independently —NH— or a bond and each instance of R43 is independently —NH— or —NH—NH—.

    Abstract: A method for forming a polyarylene sulfide is provided. The method comprises supplying a waste composition to a vessel, the waste composition containing arylene sulfide byproducts, such as an arylene sulfide oligomer, cyclic polyarylene sulfide, and/or fine polyarylene sulfide particles. The arylene sulfide byproducts are heated to a temperature of from about 260° C. to about 285° C. in the presence of a sulfur reactant, thereby forming a high molecular weight polyarylene sulfide having a number average molecular weight of about 2,000 Daltons or more.
