Synthetic Methods and Applications of Functional and Reactive Silicone Polymers

Siloxane polymers (widely known as silicones) are ubiquitous materials with a wide range of applications, from pharmaceuticals and medical devices to nautical sealants and high temperature lubricants. This is due to its robust and advantageous properties as an inorganic-organic polymer, which differ widely from traditional polyolefin materials. In this chapter, the unique and remarkable properties of siloxane polymers will be analyzed, as well as the synthetic strategies for the preparation of traditional and functional silicones. An examination of the functions of siloxane polymers and copolymers in various industries, such as polyurethane foams and fluorosilicone lubricants, is presented. Traditional methods for crosslinking of siloxane polymers and the resulting coatings and bulk materials will be compared with recent advances in silicone coupling reactions, such as the Piers-Rubinsztajn and ‘click’ reactions. Finally, we examine the new emerging approach on the siloxane bond as a reactive functional group in its own right for the preparation of advanced non-stick resins and surfaces.
