Polysiloxanes containing cyanoethyl groups (PDMS-CN) is a useful functional polysiloxanes. In this paper a new method was employed to prepare the polysiloxane with various number average molecular weight (Mn) and cyanoethyl groups. Mns of PDMS-CN were determined by GPC and the relationships between the instrinsic viscosity ([η]) and Mn of PDMS-CN were given. The contents of cyanoethyl groups were determined by FT-IR and 1H NMR.
