UV Curable Sillicons from Acryloxymethyldimethylacryloxysilane

摘要

A facile preparation of acrylate terminated silicones by the condensation reaction between the readily available silanol terminated silicone fluids and acryloxymethyldimethylacryloxysilane is described. The simplicity of the reaction provides a practical route for the preparation of UV curable silicones. The surprising ease of the reaction between the silane and silanol is attributed to the possible hypervalent silicon transition state even though ~(29)Si-NMR evidence suggests the silane is tetracovalent.
