摘要： 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.

摘要： The invention relates to a method for preparing a dry cationic hydrogel polymer product. The method comprises polymerization of a reaction mixture comprising ethylenically unsaturated monomers in presence of water and initiator(s) by radical polymerization and obtaining a hydrogel polymer. The hydrogel polymer is comminuted by chopping or shredding, and dried, whereby a dry hydrogel polymer product in powder form is obtained. At least one cationic reverse phase emulsion polymer is added to the hydro polymer at the comminuting step. The invention relates also to a dry cationic hydrogel polymer composition prepared by the method and its use.

摘要： A method for purifying a reclaimed polymer, such as a polymer reclaimed from post-consumer use or post-industrial use, is disclosed. The method involves obtaining the reclaimed polymer and contacting it at an elevated temperature and pressure with a fluid solvent to produce an extracted reclaimed polymer. The extracted reclaimed polymer is dissolved in a solvent at an elevated temperature and pressure to produce a polymer solution, which is purified at an elevated temperature and pressure by contacting the polymer solution with solid media to produce a purer polymer solution. A purer polymer is then separated from the purer polymer solution.
