Abstract

An alkenyl- or crosslinkable silyl-terminated vinyl polymer is provided. Such a functional group is introduced into its terminus at a high ratio, not via sulfur atoms. Those polymers can be prepared by polymerizing a vinyl monomer for obtaining a halogen-terminated vinyl polymer, and then substituting an oxy anion or carbanion having such a functional group for the terminal halogen of said polymer.
