摘要： The invention relates to a biocompatible, non-biodegradable, and non-toxic polymer of formula (I), comprising of three monomeric units, selected from 1-Vinylpyrrolidne (VP), N-Isopropylactylamide (NIPAM), and ester of Maleic anhydride and Polyethylene glycol (MPEG), cross-linked with a bi-functional vinyl derivative, of high purity and substantially free of respective toxic monomeric contaminants, and a process for preparation thereof. The invention further relates to nanoparticulate pharmaceutical compositions of poorly water-soluble drugs or compounds comprising the polymer of the invention, which are safe, less-toxic and convenient for bedside administration to patients in need thereof. Furthermore, the invention relates to a highly selective method for preparation of nanoparticulate pharmaceutical compositions of poorly water-soluble drugs or compounds.

摘要翻译： 本发明涉及式（I）的生物相容性，不可生物降解的和无毒的聚合物，其包含三种单体单元，其选自1-乙烯基吡咯烷酮（VP），N-异丙基丙烯酰胺（NIPAM）和马来酸酐的酯和 与双官能乙烯基衍生物交联的聚乙二醇（MPEG），其纯度高，基本上不含有毒的单体污染物及其制备方法。 本发明还涉及难溶于水的药物或包含本发明聚合物的化合物的纳米颗粒药物组合物，其对于有需要的患者的床边给药是安全的，毒性较小且方便的。 此外，本发明涉及用于制备难溶于水的药物或化合物的纳米颗粒药物组合物的高选择性方法。
