    摘要: Thioaminal polymers are made from hexahydrotriazine precursors and dithiol precursors. The precursors are blended together and subjected to mild heating to make the polymers. An amine scavenger is used to remove amine byproducts from the reaction, thus promoting polymer growth to high molecular weight. The polymers have the general structure wherein each R1 is independently an organic or hetero-organic group, a plurality of R2 groups are substituents having molecular weight greater than about 120 Daltons, and n is an integer greater than or equal to 1. The polymers may be functionalized by adding a thiol-reactive group to either end or both ends.
