Hydrosilylation has been carried out between Si-H terminated polydimethylsiloxanes with narrow molecular weight distribution and protected 3-allyloxy-1,2-propanediol,and after subsequently alcoholyzed,α-{3-[(2,3-dihydroxy)propoxy]propyl}-ω-butyl -polydimethylsiloxanes with varying number of((Si(CH_3)_2-O) unit were obtained.At each step,the produced compounds were carefully characterized.The results showed that each step was successfully carried out and target products were achieved.
