The preferential surface segregation of one component in a polymer blend has been used to modify surface properties in a controlled way. Most of surface segregation studies are based on the interaction between the additive chain ends and the bulk polymer at the surface. Still, additives having loop-typed topology without chain ends have not been used. In this study, an additive platform structure having loop-type topology without chain ends was designed for the surface modification of polymers. A series of cyclic additives were synthesized through a ring-expansion cationic polymerization. In addition, allyl vinyl ether as the monomer enabled the addition of functional groups to the cyclic pendant. The study was expanded to be merged with polymer brush grafting technologies through the conjugation of initiators to the additives for surface-initiated radical polymerization. This work not only extends the scope of the surface segregation area but also can replace the existing biomedical coating.
