摘要：

The copolycondensation of commercially available disilanols (PDMS), having various molecular weights, with a fluorinated grafted triethoxysilane and a vinyl grafted triethoxysilane led to the synthesis of a series of polysiloxanes. These polysiloxanes were thus bearing fluorinated grafts being linked to the silicone backbone through urethane groups. The structure of the final products was determined by IR, C-13 and H-1-NMR spectroscopies. The properties of these polymers at high and low temperatures are compared to those of PDMS and poly(methyltrifluoropropyl)siloxane. These products exhibit very good release properties and better properties the longer the silicone chain. (C) 1996 Elsevier Science Ltd
