Carbosilane dendrimers with a silicon branch point in an exclusively carbon-silicone skeleton are non-polar, inert, neutral, thermally and hydrolytically stable compounds. The main objective of the present study is to create prerequisites for the synthesis and systematic study of carbosilane dendrimers with a siloxane shell, which is characterized by the absence of specific interactions such as hydrogen bonds and other polar interactions. It will allow to obtain new data both from the mutual influence of silicone branched structure in the dendrimer shell on the intermolecular interaction, and on the behavior of the molecules separately. In this work, a homologous series of carbosilane-siloxane dendrimers from 4 to 7 generations which include carbosilane dendrimers in the core with siloxane branched dendrones of 1 and 2 generations in the shell of macromolecules will be obtained. We will represent the synthesis and exploration of these dendrimers by NMR, GPC, Langmuir–Blodgett. Also the jump in viscosity was observed on the flow curve between the 4 th and 6 th generation of the carbosilane-siloxane dendrimers. This data confirms the general pattern of the formation of a network of entanglement in high- generation carbosilane dendrimers.
