摘要：

In this study we report the synthesis of carbosilane dendrimers of the 1 st, 3 rd and 6 th generations, containing 2 - phenylethyl external fragments in the outer layer. Also, we prepared composite materials from polystyrene and the obtained dendrimers. The composite glass transition temperature strongly depends on the generation number and the filler content. A previously developed theoretical model for the glass transition temperature change caused by nanosized filler of a core-shell type matches the experimental data.
