Procedure
The (Cl3SiCH2CH2CH2)3B functional initiator was prepared by hydroboration of allyltrichlorosilane with boron hydride (3:1 mole ratio). Hydroboration reaction was conducted at 0° C. for 4 hours in tetrahydrofuran (THF). In a typical example, the reaction was carried out in dried flask containing 20 ml dried THF and 8.7 ml (0.06 mol) allyltrichlorosilane. The solution was then cooled down to 0° C., and 20 ml (0.02 mol) of 0.1 M boron hydride in THF was then dropped slowly via the air-tight syringe into the reaction flask. The solution was stirred at 0° C. for 4 h. After that the THF was removed under high vacuum pump to obtain about 82% yield tri(trichlorosilyl propyl)borane initiator.
