A method for synthesizing growth ring-type dendritic macromolecules starting from siloxane polymer with Si-H bonds [Me3SiO(MeSiOH)(n)SiMe3] as the core and dichlorovinylsilane, dichloromethylsilane, lithium phenylacethylide, and allylmagnesium bromide as the building blocks is described. The siloxane polymer was produced to the second dendritic generation by the repetition of hydrosilation and alkenylation as well as by an alkynylation process.
