通过T8硅氧烷六面体选择性的硅氢化反应, 制备了一个具有八个激化位的硅氧烷六面体巨激化体, 并利用原子转移自由基聚合(ATRP)技术合成含无机核的星型聚丙烯酰胺高分子. 这类高分子具有良好的水溶性, 展现出分子量高度可控性和窄的分子量分布.

关键词: 星型高分子, 聚丙烯酰胺, 原子转移自由基聚合, T8硅氧烷六面体

A new silsequioxane based macro-initiator with eight initiating sites was prepared from a selective hydrosylation of T8 silsequioxane, and used to synthesize water soluble star polyacrylamide containing inorganic-core through atom transfer radical polymerization (ATRP). The generated polymers exhibit good solubility in water, controlled molecular weights and narrow polydispersity.

Key words: star polymer, polyacrylamide, atom transfer radical polymerization (ATRP), siloxane based six-faced structure
