Multiple charged ionic compounds derived from polyamines and compositions thereof and methods of preparation thereof
Disclosed herein are the multiple charged cationic or anionic compounds, methods of making thereof, and articles or compositions comprising thereof. The disclosed multiple charged cationic or anionic compounds are derived from polyamines through two reactions: an aza-Michael addition with an activated olefin having an ionic group and a ring-opening reaction with an epoxide.
RENEWABLE POLYMERS AND RESINS AND METHODS OF MAKING THE SAME
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.

USE OF DI-IONIC COMPOUNDS AS CORROSION INHIBITORS IN A WATER SYSTEM
Disclosed herein are the methods of using di-cationic or di-anionic compounds, which are derived from primary amine through an aza-Michael addition with an activated olefin, in a corrosion control composition to mitigate corrosion of a surface in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for mitigating corrosion for a metal surface in water systems.
