Abstract:
1. Polymer particles comprising: at least one LCST polymer that displays a lower critical solution temperature, in aqueous media, that is between 10 to 90° C., the LCST polymer being the polymerisation product of one or more monomer selected from the group consisting of polymerisable alkyleneglycol acrylate monomers and polymerisable alkyleneglycol methacrylate monomers, wherein the polymer particles are obtainable by a method selected from at least one of an emulsion method, diffusion method and evaporation method carried out in the presence of said LCST polymer as a surface-engineering surfactant, and wherein the polymer particles have a bulk phase or core of biodegradable polymers.
