Polymer particles prepared from polymerisable alkylene glycol (meth) acrylate monomers

Polymer particles comprising:

• a biodegradable polymer core, and
• a thermoresponsive biocompatible co-polymer corona, wherein the co-polymer is a LCST polymer that displays a lower critical solution temperature, in aqueous media, that is between 10 to 90° C., this LCST polymer being the polymerisation product of two or more monomers selected from the group consisting of polymerisable alkyleneglycol acrylate monomers and polymerisable alkyleneglycol methacrylate monomers.
