Abstract

Telechelic polymers having two reactive functional groups at the same polymer chain end are disclosed. These polymers can be prepared by combining a cycloborane initiator, at least one free radical polymerizable monomer and oxygen to form a polymer segment having a borane residue at one end of the polymer segment resulting from the cycloborane initiator; and converting the borane residue to at least two functional groups to form the telechelic polymer.
