Abstract

Particles comprising a branched polymer and either a block copolymer or a linear dendritic hybrid represent a category of useful materials. They may be used in for example drug delivery applications. They may be prepared by a method comprising the steps of: dissolving the branched polymer and block copolymer or linear dendritic hybrid, and optionally other component(s), in a solvent to form a solution; adding said solution to a different liquid; and removing said solvent to form a dispersion of co-precipitated particles.
