Core-first star synthesis compounds

The so-called core-first method has been extensively used for the synthesis of various kind of star-shaped polymers, water-soluble or not. The functionalizable outer end of the branches offers an original access to a large scope of macromolecular architecture star-shaped polymers with copolymeric branches, functional star-shaped polymer networks, etc. The in-out method combines the advantage of the arm-first method and the core-first method allowing good control of the structure and the presence of functionalizable outer end of the branches. Different unsaturated compounds have been used to generate the core, such as DVB and DPE, the latter compound giving access to star-shaped terpolymers.
