Reactive Silicones as Multifacetic Materials Suranjan Sikdar and Sukanta Majumdar
Abstract Silicones are very useful materials that vary in their structure, reactivity and physicochemical properties, although they contain a covalent bond between silicon and the carbon atom of an organic group. Most silicone polymers are artificial because the organo-silicon bond is not found in nature. The study of the silane coupling agent has also revealed that it plays an important role in improving the durability and performance of silicone as softeners, especially the type of linear reaction. The improvements in wrinkle recovery are mainly due to the formation of an elastic silicone polymer network, which traps fibers within its matrix, which improves the fabric’s ability to recover from deformation. The results have indicated several areas of technical application for the modified fabric, such as barrier textiles with permeability control, localized modification of the mechanical properties of the fabric. The enormous opportunities in the design, synthesis and modification of the physical and chemical properties of polymers have made them the fastest growing group of materials, having great importance and possibilities for applications in cosmetology, medicine and pharmacy. In this chapter, we focus on a general description of the silicone polymers used, including polydimethylsiloxane (PDMS), with respect to their physicochemical properties and factors affecting their current applications. Finally, the use of silicone polymers as excipients in the technology of various products, e.g. skin adhesive patches and controlled drug delivery systems, are presented. The synthesis of a new class of reactive silicone resins containing vinyl and methacryloxypropyl substituents has also been discussed below. Organo- functional silanes, their chemistry, properties, uses and the main laboratory experiments that may also be of interest to the food and beverage industry.

10.1 Introduction Today, the term silicone is used principally in conjunction with the technical applications of polysiloxanes (Hill 2005). Silicones have specific properties compared to other similar types of polymers due to their bonding pattern with organic groups and inorganic atoms. The Si-O-Si link is best represented by the term ‘siloxane’ (Mojsiewicz-Pieńkowska et al. 2016). Strictly speaking, all silicones should be correctly referred as ‘polysiloxanes’ (Hill 2005). Silicones are a diverse family of spe
