Two variants of poly(dimethylsiloxane‐co‐methylhydrosiloxane) polymers were functionalized with three different phenol derivatives (3‐pentadecylphenol, 4‐tert‐octylphenol and phenol) to synthesize six new phenoxylated siloxane polymers using the Piers−Rubinsztajn process/chemistry. The new polymers ranged in physical appearance from waxy solids to liquids. It has been shown that the different phenoxy fragments directly influence the physical and thermal properties of the polymers in a predictable and rational way. The variant based on 3‐pentadecylphenol is of particular interest as it utilizes a naturally sourced and sustainable material from cashew nut shell oil.
