Binary catalytic systems combining innocuous metals (yttrium, zinc, magnesium, or calcium) and bifunctional alcohols (acting as transfer agents) were developed to promote the immortal ring\u2010opening polymerization of lactide directly in styrene. Up to 20\u2009000\u2005equivalents of lactide were polymerized (metal catalyst loading of 50\u2013100\u2005ppm) in a controlled fashion in the presence of 10\u2013100\u2005equivalents of a double\u2010headed transfer agent to give as many end\u2010functionalized poly(lactide) macromolecules that can be used eventually as macroinitiators for the controlled nitroxide\u2010mediated polymerization of styrene.
