Side Group Modified Polysiloxanes

摘要: The chemistry and technology of siloxane-based polymers, or silicones, is a very broad still growing research area owing to their many unique properties such as thermal oxidative stability, low surface tension, gas permeability, excellent dielectric properties, physiological inertness moisture resistance [1–3]. Because these silicones find tremendous number applications. Modifications polysiloxane side groups are extensively explored in order obtain polymers with special make them chemically active, thus giving access new industrial Polysiloxanes may be silicon-functional, i.e. the functional group, X, directly attached silicon atom (Si-X), organofunctional, group fixed via Si-C alkylene arylene (Si-R-X). most important include hydrogen, vinyl, chloro, hydroxy, mercapto, alkoxy, cyano, methacryloxy amino groups. There three general routes modified polysiloxanes: modification polysiloxanes, polycondensation bisilafunctional monomers ring-opening polymerisation cyclosiloxanes.
