A new synthetic procedure is described for the preparation of dendritic polyethylene brushes with polysiloxane as the main chain, describing for the first time that it is possible to simply and efficiently prepare highly branched architectures for this type of polymer. Furthermore, as a result of the polymer brush architecture, polyethylene acts as the side chains and SiOSi as the backbone. The number average molecular weight (Mn) of the polyethylene brushes, which is determined using a multiple angle laser light scattering detector, increases from 5946 to 27 684 g mol−1 while retaining relatively narrow polydispersities (1.5–2.4). The polymer brushes are characterized by solid 29Si NMR and high‐temperature 1H NMR spectra. In addition, X‐ray photoelectron spectroscopy and gel permeation chromatography were used to confirm the structure.
