Recent Progress in the Structure and Condensed Phase of Hyperbranched Polymers

There is a great deal active end group existing in hyperbranched polymer, which condensed phase structure will be transformed by virtue of modification and functionalization of active end group of hyperbranched polymer. The special structure and properties of hyperbranched polymer were introduced in this paper. The present investigation of the conformation and the condensed phase structure were summarized. Its molecular structure parameters were discussed systematically, including branching glass transition temperature, intrinsic viscosity and so on. characterization were illustrated extensively. Furthermore, the degree, molecular weight distribution, molecular size, On these bases, physical chemistry properties and article reviewed the contributions of worldwide scholars and made some predictions for the future developments and process of hyperbranched polymer.
