Summary Polymerisations of either enantiomer of commercially available methyl β-hydroxyisobutyrates 1a and 1b were carried out. Ti(OBun)4 catalysed transesterification of the neat monomer generated either polymer 3 at lower temperatures (∼100°C) or homochiral macromonomer 2 at higher temperatures. Under optimal conditions for the preparation of the macromonomer 2, a soluble material (Mn 3600, Mw 7000) was produced which displayed high crystallinity as judged by X-ray powder diffraction analysis.
