Abstract
Processes, and related compositions, to form a siloxane modified olefin-based polymer, a silane modified olefin-based polymer, or a silane, each process, as described herein. Each process forms an Si—C bond through insertion of silyl vinyl into a metal carbon bond. The silyl vinyl double bond directly inserts into the metal-carbon bond to form a new, for example, alkyl-Si linkage.
