Organic polymer particles containing a poly (oxazoline) stabilizer and use of poly (oxazoline) for stabilizing organic polymer particles

摘要

Water-soluble poly (oxazoline) and polyolefin, polyvinyl aromatic, polyvinyl ester, polyester, polyamide, polyimide, polycarboxylic acid, polycarboxylic acid ester, polycarboxylic acid amide, polynitrile, polysulfonic acid, polyketone, polysulfone, polymer polyol, polyurethane , A protein, a polymeric carbohydrate, a nucleic acid, or an organic polymeric particle selected from the group of mixtures of two or more of these polymers. The water-soluble poly (oxazoline) acts as a stabilizer for the polymer particles, and it is particularly advantageous that it can be used as a stabilizer during freeze-drying of the polymer aqueous dispersion.
