Abstract
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.
Claims17
A method for producing a polymer, comprising:
- forming a reaction mixture comprising a non-polar solvent and an imine compound comprising electron withdrawing or accepting groups;
- adding a multifunctional nucleophile to the mixture;
- and
- heating the mixture at a temperature from about 50° C. to about 150° C. to produce a polymer.

A method for producing a polymer, comprising:
- forming a reaction mixture comprising a non-polar solvent, a formaldehyde, and an imine precursor compound comprising electron withdrawing or accepting groups;
- reacting the imine precursor compound with the formaldehyde to form an imine compound;
- adding a multifunctional nucleophile to the mixture;
- and
- heating the mixture at a temperature from about 50° C. to about 150° C. to produce a polymer.

A method for producing a polymer, comprising:
- forming a reaction mixture comprising a non-polar solvent, a formaldehyde, and an aminobenzene compound;
- reacting the aminobenzene compound with the formaldehyde to form an imine compound;
- adding a multifunctional nucleophile comprising an atom selected from the group consisting of:
- C, Si, Ge, Sn, N, P, As, Sb, O, S, Se, and Te to the mixture;
- and
- heating the mixture at a temperature from about 50° C. to about 150° C. to produce a polymer.
