Abstract: A networked silicone is disclosed. The networked silicone comprises crosslinked strands of looped organosilicon compounds. A composition for preparing the networked silicone is also disclosed, and comprises (A) a looped organosilicon compound, (B) a crosslinking organosilicon compound, and optionally (C) a catalyst. Additionally, a method of preparing the networked silicone is disclosed, and comprises reacting the looped organosilicon compound (A) and the crosslinking organosilicon compound (B), optionally in the presence of the catalyst (C), to give the networked silicone. A reaction product comprising the networked silicone is also disclosed. The reaction product is prepared from the composition and/or in accordance with the method, and may be a cured product. Additionally, a composite article and a method of forming the same are disclosed.

Abstract: In some embodiments, macromolecules and related methods are provided. In some embodiments, an iterative growth process may be used to form a macromolecule comprising one or more repeat units comprising a functionalizable pendant group, with precise control over mass, length, backbone sequence, pendant group sequence, and/or stereochemistry, amongst other features. Macromolecules (e.g., non-natural macromolecules) form from the iterative growth process, described herein, may be used for a wide variety of applications, including the delivery of active agents.
