Hyperbranched polymers are prepared by a process in which a monomer having the form Ax is reacted with another monomer of the form By, where A and B are functional groups that do not react with themselves, but do react with each other. The process allows synthesis of hyperbranched polymers having a single type of terminal functional group from comonomers, each of which has a single type of functional group. The invention allows greater flexibility in the preparation of a larger variety of different hyperbranched polymers and enables hyperbranched polymers to be prepared at a lower cost as compared with conventional processes using monomers having two types of functional groups that react during polymerization. |
