| 摘要 |
The invention relates to a process for the production of pseudolatices or micro- and/or nanoparticles, in which a polymer is crystalline, partially crystalline or amorphous, is selected from cellulose derivatives, poly(meth)acrylates, shellac, polylactides, polylactide/polyglycolide mixtures, polyhydroxy butyric acids or polycyanoacrylates and is heated to a temperature above its glass transition temperature and then high-pressure homogenized in water or an aqueous buffer solution and this suspension is converted, if necessary, into micro- and/or nanoparticles by drying. Medicaments can be worked into the pseudolatices, micro- and/or nanoparticles.
