A paper by Yan Cong*, Zhaoxia Li*, Pei Bian* and Thomas J. McCarthy* was recently published in Macromolecules. This paper, entitled Isomeric Silicones: Reactive Phenylsilsesquioxane-based MT Resins and Comments Concerning the Structure of Phenylsilsesquioxane Homopolymer, explains how reactive controllable viscosity isomeric silicone copolymers can be injection molded to form monolithic objects, printed to form 2D or 3D shapes, or coated to form films or encapsulants.
