The present disclosure relates to methods for producing polymers and resins, the method including a first reacting of at least a first diamine with a first carbonate-containing compound and a second carbonate-containing compound to produce at least one of the polymer or the resin, where the first reacting is according to

##STR00001##

each of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 include at least one of a hydrogen atom, a methyl group, a saturated hydrocarbon chain, and/or an unsaturated hydrocarbon chain, and R comprises at least one of a carbon atom, a saturated hydrocarbon chain, and/or an unsaturated hydrocarbon chain.

A hydrogen sulfide donor in an organic salt form and a preparation method thereof. The hydrogen sulfide donor exists as a salt formed by organic compounds with an alkaline motif and hydrogen sulfide with weak acidity. The hydrogen sulfide donor features with a simple structure, and an easy preparation method. Moreover, hydrogen sulfide donors in different forms can be prepared according to research and development needs. After the hydrogen sulfide donor enters an organism, the process of in vivo dissociation and hydrogen sulfide supply is simple, rapid, and effective, and there is no requirement for enzyme or any other complicated condition, and thus, the hydrogen sulfide donor has a great application prospect and value.
