Octamethylcyclotetrasiloxane(D4)and N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane(KH-792) were chosen to synthesize aminopolysiloxane by bulk anion polymerization,with KOH as catalyst,hexamethyldisiloxane(MM)used as end capping agent,and dimethyl sulfoxide(DMSO) utilized as accelerating agent.

We synthesized (SI)_4Si star-type block copolymer with styrene,isoprene and silicon tetrachloride as raw materials,tetrahydrofuran as molecular weight regulator,cyclohexane as solvent,and n-BuLi or naphthalene lithium as initiating agent by anion polymerization method with three steps.

Synthesis methods of PFPE are mainly anion polymerization of perfluoro-epoxide and photo-initiated oxidation of perfluoro-olefine.
