This lecture summarizes some of our recent results about reactions with synthetic polymers. By cationic ring-opening polymerization of 4H, 7H-1,3-dioxepin a linear polyacetal containing one C-C-double bond per repeating unit is obtained. Copolymerization of this monomer with trioxane or dioxolane ...

aAlthough many (3,4)-connected networks in coordination polymers have been reported, to our best knowledge, this type of topology defined by compound 3 has not been observed in any other coordination polymers. 虽然许多(3,4) -连接的网络在协调聚合物在所有其他协调聚合物,向我们的最佳的知识报告,...
They are made by polymerization, the process of chemically linking many smaller molecules to form a larger molecule that has different physical features. Some polymers, such as proteins, occur naturally.Plastic is a key component of many products. When heated into an almost-liquid form, plastic ...

Since the inception of the oil and gas industry, many natural polymers have been used. Examples include cellulose, starch, and lignin (Kraak 1992). Some of these polymers were either used as extracted in their pure or ultra-pure forms or used after little modification (examples are cellulose ...
