Abstract

Hyperbranched, biodegradable PCL-based polymers are obtained through a random but invasive migration of an in-situ generated carbene end group which is unmasked via the thermolysis of its precursor diazirine moiety. These hyperbranched cores are used as macroinitiators for ‘grafting-from’ polymerisation using controlled radical polymerisation leading to amphiphilic copolymers which can subsequently be self-assembled into spherical core-shell micelles.
