    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: Aspects of the present disclosure relate to Schiff base oligomers and uses thereof. In at least one aspect, an oligomer is represented by Formula (I) wherein each instance of R4, R5, R6, R7, R8, R10, R11, R12, R13, and R14 is independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkoxyl, aryloxyl, ether, and heterocyclyl. Each instance of R9 of Formula (I) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and ether. Each instance of R28 and R29 of Formula (I) is independently selected from the group consisting of hydrogen, alkyl, and aryl. Each instance of R33 of Formula (I) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and a bond. Each instance of R41 of Formula (I) is independently —NH— or a bond and each instance of R40 is independently —NH— or —NH—NH—.

    Abstract: A crosslinking agent that is an ungelled reaction product of (a) at least one aminoplast resin and (b) at least one tall oil rosin wherein the crosslinking agent is essentially free of active hydrogen functional groups and has a glass transition temperature of at least 10° C. is disclosed. Methods for preparing crosslinking agents are also disclosed. Further provided is a curable powder coating composition including a polymer having a glass transition temperature of at least 30° C. containing reactive functional groups and the present crosslinking agent; a multilayer composite coating composition and substrates coated therewith are also disclosed.
