Synthesis, Characterization, and Properties of New Fluorosilicone Block Copolymers

Abstract

In this work, perfluorocyclobutyl (PFCB) aryl ether block dimethylsilioxane polymers were prepared via the step-growth addition polymerization of discreetly sized PFCB prepolymers and carbinol (hydroxyl) terminated silicones. These hybrid fluorosilicone polymer systems displayed high thermal stability, are entirely amorphous, and solution processable producing transparent films with high optical clarity. The synthesis, characterization, thermal analyses, and current scope of hybrid PFCB aryl ether polymer systems are discussed.
