Method A (Eq. 1) is the conventional addition polymerization process through the double bond, analogous to the addition polymerization of open-chain olefins. The product obtained by Method A possesses alicyclic moieties as constituents of the polymeric repeat units. A second polymerization scheme, ...

Chapter 15:Polyester functionalized carbohydrates via organocatalyzed ring-opening polymerization One of the preferred strategies for this purpose is the carbohydrate initiated ring-opening polymerization of cyclic esters, due to its controlled character. Metals, enzymes and organic molecules mediated ring-open...
The invention relates to a category of cyclic ester open loop polymerization catalyst and method for preparation, it also relates to the process for polymerizing racemic lactide by using these catalysts, wherein the catalysts are the product of the reaction between Schiff's base and aluminium trie...
