Abstract
A method for providing a polymer having terminal functionality that includes at least one sulfur atom and at least one silicon or tin atom involves reacting a terminally active polymer with a cyclic compound that includes in its ring structure at least one Si or Sn atom and at least one S atom, optionally at adjacent positions of the ring structure.
Claims20
A method for providing a polymer having terminal functionality, said method comprising reacting a terminally active polymer with a cyclic compound that comprises in its ring structure one or more sulfur atoms and one or more M atoms where M is silicon or tin, thereby providing said polymer having terminal functionality, wherein at least one of said one or more M atoms is bonded to at least one halogen atom or a secondary amine group.
