Polymer particles via top-down processes

Production of functional polymer particles via liquid-based top-down processes (A01), CRC814

Funded by Deutsche Forschungsgemeinschaft (DFG) – Project number 6137593

Aim of this sub-project of CRC 814 “Additive Manufacturing” is process intensification and optimization of process parameters in view of minimization of alteration of intrinsic polymer properties due to processing. A continuous wet grinding – separation circuit will allow for an increased yield of the target particle size fraction and optimal control of particle residence time. The melt emulsification approach, amongst others, will be performed for low-viscous polymer waxes. The obtained particles will be subjected to solid state polymerization. Precipitation will be utilized for production of microparticle filled systems.
