Polymerization of cyclosiloxane initialed by cyclotrisilazane trilithium salt is successfully carried out.The polymer is characterized by NMR
IR
GPC and viscosity measurement.It is confirmed that the polymer is star shaped polymer.The study of kinetics of polymerization shows that reaction order with respect to D 4 is 1.The promoter DMF has a stronger effect on polymerization than diglyme.
