Abstract

The invention relates to a method for preparing a multistage polymer particle composition for curable formulations comprising subjecting multistage polymer particles to a contaminant-reduction process that reduces a level of at least one contaminant species present in the multistage polymer particles, such as potassium, sodium, phosphorus, sulfur, or combinations thereof. The contaminant-reduction process may include washing the particles in water and optional acid or performing a solvent-exchange process including an organic solvent and optional acid. The multistage polymer particles include a core polymer, an inner shell polymer surrounding the core polymer, and an outer shell polymer surrounding the inner shell polymer. The compositions may be formulated into curable formulations for various applications such as 3D printing or used to prepare cured compositions from the curable formulations.
