The disclosure describes new compositions and methods related to polyaminals and related polymers. The compositions are useful as therapeutic/drug conjugates, self-healing materials, reversible crosslinking materials, degradable hydrogels, protective coatings, and as metal scavenging agents. New atom efficient synthetic schemes are disclosed, which yield previously unobtainable high molecular weight polyaminals.

Disclosed herein are dithiol-based polymers and cyclic compounds that can be formed therefrom. The cyclic compounds also can be used to regenerate recycled polymers. Methods for making native and recycled polymers are described herein, along with methods for using the compounds of the present disclosure to provide crosslinked vitrimer-like products.
