| Abstract: | The 29Si NMR spectra of a, w-bischloro-and a, w-bis (diethylamine)-polydcmethylsilanes(I) (X=Cl,NEt2;n=0,1,2,3,4,5,6)andcyclosilanes(R2SiO)n(Ⅱ),cyclo-silazanes(R2SiNH)n, (Ⅱ) (R=Me,Ph;n=3,4) have been measured.The effets of n and X(X=Cl,OH,NEt2,Me) on δsi of end-and middle-groups in I and the effects of ring-size and R on δsi of Ⅱ,Ⅲ have been discussed. |
