Is P4 a Base?
Phosphazene base P4-t-Bu solution is an extremely strong, hindered, neutral nitrogen base; approximately 1018 times more basic than DBU [pKa (DMSO) 30.25].
What is the structure of Phosphazene?
Phosphazenes refer to classes of organophosphorus compounds featuring phosphorus(V) with a double bond between P and N. One class of phosphazenes have the formula RN=P(NR2)3. These phosphazenes are also known as iminophosphoranes and phosphine imides.

What are the properties of phosphazene?
Although the substituents are the main influence on the polymer’s physical properties, phosphazene polymers can provide the following characteristics: Bio-compatibility, Flexibility, High Dipole Moment, Broad Range of Tg (glass transition temperature), Chemical Inertness, Mechanical Strength, Solvent Permeability or …
How are phosphazene prepared?
2.2. The poly(dichlorophosphazene) (PZ) was obtained by melt ring-opening polymerization of hexachlorocyclotriphosphazene (HCCP) under vacuum at 250°C for 3 h. After this time, the polymer was dissolved at room temperature in anhydrous THF, and it was separated by precipitation into n-heptane.
Is P4 metal or nonmetal?
Tetraphosphorus is a member of tetraatomic phosphorus. A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.
Is phosphorus a metal?
Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table. This element exists in several forms, of which white and red are the best known.
What are phosphorus based chain polymers?
Polymers in which phosphorus is an integral part of the main chain, including polyphosphazenes and polyphosphoesters, have been widely investigated in recent years for their potential in a number of therapeutic applications.

Is phosphorus a metal or nonmetal?
non-metal
Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table.
What are Polyphosphazene used for?
Polyphosphazenes are polymers containing nitrogen as part of their backbone; they are commonly used in O-rings, pipelines, and seals in oil, fuel delivery, and storage systems.
What are uses of organo phosphazenes?
Poly[(organo)phosphazenes] are a unique class of extremely versatile polymers with a range of applications including tissue engineering and drug delivery, as hydrogels, shape memory polymers and as stimuli responsive materials.
Why is phosphorus p4?
Answer: Phosphorus can form a P4 white phosphorus tetrahedron because it can form three bonds. The most stable allotrope of phosphorus, red phosphorus, is a cross-linked, polymeric chain of atoms. P has a high atomic size and a low tendency for forming triple bonds.
Why phosphorus is not a metal?
The phosphorus generally shows +3 and -3 as its oxidation state as by removing three electrons or by adding three electrons it can achieve the stable electronic configuration. So the answer is reactive. Phosphorus is a very reactive non – metal.
What is polymeric backbone silicones?
The backbone is a chain of alternating silicon and oxygen atoms. Each silicone has two groups attached to it, and these can be any organic groups. The picture at the top of this page shows methyl groups attached to the silicon atoms. This polymer is called polydimethylsiloxane. It is the most common silicone.
