Abstract
Organofunctional silanes with more sterically hindered substituents at the silicon atom than the typical methoxy (ethoxy) group have lately been frequ ently used as silane coupling agents, in polymer coupling systems, sol-gel processes and also as interpenetrating polymer network substrates. New and very efficient synthetic ways leading to organofunctional silanes of the ab ove type with methacryl, amine, chloro and isocyanato functional groups are proposed here. Catalytic transesterification and/or alcoholysis of chlorop ropyltrialkoxysilanes followed by nucleophilic substitution has been employ ed. Copyright (C) 2001 John Wiley & Sons, Ltd.
