List the following group of monomers in order of decreasing ability to undergo cationic polymerization.
A3
Anionic polymerization of styrene is generally known to produce polymers with a narrow molecular weight distribution. Explain the reason for this.
A boron-siloxane cross linked polymer was formed from the reaction between dichlorodimethylsilane in diethyl ether with deionised water. Which was neutralised with sodium bicarbonate solution before being turned into a polymer upon the addition of boric acid. What is the structure of the polymer synthesised and what is the molecular weight of one monomer unit of this boron-siloxane cross linked polymer?
