reversible covalent and non‐covalent molecular interactions. It is demonstrated that amine–boronate complex formation provides a simple and flexible route to reversible crosslinked silicones. A variety of network structures were prepared by use of terminal and pendantly functionalised silicone boronates and amines. The crosslink density was quantified using a combination of Shore‐hardness measurements, swelling
