Dumbbell‐Shaped, Graft and Bottlebrush Polymers with All‐Siloxane Nature: Synthetic Methodology, Thermal, and Rheological Behavior

A methodology for synthesizing a wide range of dumbbell‐shaped, graft and bottlebrush polymers with all‐siloxane nature (without carbosilane linkers) is suggested. These macroarchitectures are synthesized from SiOH‐containing compounds—silanol (Et 3 SiOH) and siloxanol dendrons of the first and second generations, with various peripheral substituents (Me or Et)—and from linear siloxanes comprising terminal and internal SiH groups by the...
