Abstract
The present invention provides novel “hybrid” silyl-terminated polymers that contain at least two different reactive end-capping groups. The “hybrid” silyl-terminated polymers of the present invention are produced by a novel single multi-step end-capping reaction of at least one silanol-terminated polymer with at least two silanes in the presence of a catalyst.
