Hydrosilylation of polymethylhydrogenosiloxanes in the presence of functional molecules such as amines, esters or alcohols

Abstract

This article presents an overview of the methods used in our laboratory to successfully perform hydrosilylation reactions on polymethylhydrogenosiloxane polymer in the presence of several functional molecules, such as esters, acids, amines, alcohols or carbamates. The used catalysts are platinum based homogeneous systems. In each case, experimental parameters such as choice of catalyst, catalyst/ Si-H functions ratio, temperature have been examined. Also, a detailed kinetic study was performed in the case of liquid crystal molecules in order to better characterize the system. © 2008 Springer Science+Business Media B.V.
