Rubber. 1. The word “rubber” immediately brings to mind materials that are highly flexible and will snap back to their original shape after being stretched. . The term “rubber” was coined for this material by the English chemist Joseph Priestley, who noted that it was effective for removing pencil marks from paper. Plastic bag.

Dynamic covalent chemistries are an exciting class of reactions that have gained attention on account of their ability to access reprocessable and healable polymer networks. We have developed a series of dynamic covalent networks based on reversible thia-Michael reactions (Fig A) and disulfide exchange reactions (Fig D).. Polyethylene is the most commonly used plastic in the world and can be made to have diverse properties. . Over 90 million metric tons of polyethylene are produced globally each year.. Polyethylene is used in power transmission, food packaging, consumer goods, electronics, and household goods.. : The. . HOST. -Reduce-. Polytech. -. ACS. . trial. Hyo-Soo Kim, MD/PhD.
