Abstract
The disclosed technology provides a thermoplastic copolymer comprising: a plurality of difunctional triketone species; (b) a plurality of a first diamine species, wherein the first diamine species contains one or more primary amine groups and/or one or more secondary amine groups, and wherein the first diamine species does not contain a tertiary amine group; a plurality of a second diamine species, wherein the second diamine species contains one or more primary amine groups and/or one or more secondary amine groups, wherein the second diamine species does not contain a tertiary amine group, and wherein the second diamine species is different than the first diamine species; and optionally, a plurality of monofunctional amine-reactive groups. Some embodiments provide segmented thermoplastic copolymers. Methods of making and using the thermoplastic copolymer are also described, including depolymerizing the thermoplastic copolymer to form recycled monomers. The recycled monomers may then be repolymerized in a closed-loop system.
