Abstract
Official abstract text for this publication.
The invention relates to a process for preparing (meth)acrylamido-functional silanes.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing an acrylamidoalkyl-functional silane, the process comprising: reacting an aminoalkyl-functional alkoxysilane of formula I or a mixture comprising at least two silanes of the formula I with an acrylic anhydride of formula IV to obtain an intermediate reaction product: (R 1 O) 3−a−b (R 2 ) a Si(B) 1+b (I) (CHR 5 ═CR 4 CO) 2 O (IV); and optionally partially removing an acrylic acid and/or reaction products of the ac…
