The present invention relates to novel block polymers comprising at least one first block and at least one second block that are incompatible with each other, have different glass transition temperatures (Tg), and are linked together via an intermediate segment comprising at least one constituent monomer of the at least one first block and at least one constituent monomer of the at least one second block. The block polymer has a polydispersity index I of greater than 2. The invention also relates to cosmetic compositions comprising the block polymers and processes for their use.
本发明涉及一种新型块状聚合物,包括至少一个第一块和至少一个与第一块不相容且具有不同
玻璃转移温度(Tg)的第二块,并通过中间段连接在一起,该中间段包括至少一个第一块的组成单体和至少一个第二块的组成单体。该块状聚合物的聚分散度指数I大于2。本发明还涉及包含该块状聚合物的化妆品组合物以及它们的使用方法。
