The invention relates to spherical particles formed by polymer chains containing approximately from 30 to 10000 monomer units derived from monocyclic polycyclic alkene polymerization, wherein at least one monomer unit is substituted by an R chain including ethylene polyoxide which is optionally covalently linked to the polymer units through a hydrolyzable bridge and substituted by a reactive function, optionally engaged in a link with an active principle or a biological molecule such as protein, wherein the chain R is covalently linked to the monomer units. The use of the inventive spherical particles for preparing pharmaceutical and cosmetic compositions or surface coatings is also disclosed.
该发明涉及由聚合物链形成的球形颗粒,其中该聚合物链含有大约30至10000个单体单位,这些单体单位来自单环多环烯烃聚合物化,其中至少一个单体单位被R链取代,该R链包括乙烯聚氧化物,该乙烯聚氧化物可以通过可水解的桥连接到聚合物单元,并且被反应性功能取代,可选择地与活性原理或生物分子(如蛋白质)结合,其中链R与单体单位以共价键连接。该创新球形颗粒用于制备制药和化妆品配方或表面涂层。
