Edy, I would recommend asking Gelest this question. We have always found them terrific at answering technical questions promptly. What are you trying to do? We are experts in functionalizing surfaces to produce hydrophobic or hydrophilic surfaces.

Does anyone knows the use of these polymers? If you do, Is it possible to mix simply them with for example Sylgard 184 in order to create a functionalized surface? Are there some examples in literature ? Here you will find the section of the Gelest catalog to which I refer: http://www.gelest.com/pdf/reactivesilicones.pdf Any contribution will be appreciated to solve my "modification" problem. Thanks to all Edy
