This phenomenon is explained by a change of the direction of primary axis of optical (deformational) polarizability in the monomer unit of polyphosphazenes with the “critical” length of side substituents. Because of that, these polymers show sharp melting points. So, they have unique properties. Corrosion control, using inhibitors like, polymerisable porphyrins and multifunctional nanocomposites, is extremely useful in many environments. These free radicals are added to another monomer forming another free radical. The inhibition effect ranged from 38.1% to 81.9% maximum at a concentration of between 0.125% to 1% before dropping sharply to between 9% and 4% at 1.25% to 1.5% concentration. A relatively low cost and easy scalable procedure was used in this article to prepare silicone composites based on high molecular weight polydiorganosiloxane copolymer and hydrophobized silica and titania nanoparticles. i. This prepolymer was prepared by a reaction of azo chromophore (dispersed red 19) containing two hydroxyl functional groups and isophorone diisocyanate (IPDI). Diamonds are almost entirely pure, carbon, where each carbon is at the center of a tetrahe-, dron composed of four other carbon atoms. These can be easily tuned by the preparation strategy: proper choice of the molecular mass and microstructure of the polymer matrix; adding or not of more or less active fillers; whether these are incorporated in the polymeric matrix (ex situ) or generated in situ; crosslinking mode (through the side or ending functional groups) or mechanism (condensation, radicalic or by hydrosilylation).
