The disconnection approach is applied to teaching of polymer chemistry. The disconnection strategy for usual polymer synthesis problem is proposed, the rules are summarized, and the usual polymer synthesis problem is categorized. These approaches made it easier for the students to handle polymer synthesis problems, to learn the method and have the ability to learn. Accordingly, a new classification of polymerization reactions is suggested, which classifies polymerization reactions into three categories by occurring between functional groups, via opening of double bonds, and by opening of rings. It is also summarized that the disconnections in polymer synthesis are usually made between the units along the main chain, between the main chain and the side groups, between the main chain and the branches, and between the main chain and the end groups, and at the position of the functional groups or the heteroatoms.
