The incorporation of an amino group into a bifunctional initiator for the cationic ring-opening polymerization (CROP) is achieved in two-step reaction. Detailed kinetic studies using 2-ethyl-2-oxazoline demonstrate initiators' eligibility CROP yielding well-defined polymers featuring molar masses about 2000 g mol-1 . Deprotection phthalimide moiety subsequent to enables introduction cyclooctyne...
