| 摘要 |
The invention relates to a process for preparing pseudolatices or micro- and/or nanoparticles, in which a polymer which is crystalline, partially crystalline or amorphous and is selected from cellulose derivatives, poly(meth)acrylates, shellac, polylactides, polylactide/polyglycolide mixtures, polyhydroxybutyric acids or polycyanoacrylates is heated to a temperature above its glass transition temperature and subsequently high-pressure homogenised in water or an aqueous buffer solution, and this suspension is, where appropriate after drying, converted into micro- and/or nanoparticles. Pharmaceutical substances can be incorporated into the pseudolatices, micro- and/or nanoparticles. |
