^aDisperse blocks are indicated with a tilde (∼) character preceding the (desired) average block lengths.

^bNumber of siloxane, methylene, or l-lactic acid repeat units.

^cCalculation based on the total number of repeat units.

^dNumber of segments based on a 110 ų reference volume.

^eVolume fraction of the crystalline block, calculated using bulk densities for PDMS (0.95 g mL^–1),^6,7 PLLA (1.29 g mL^–1),³² and tritriacontane (0.82 g mL^–1).

^fHeat effect per mole of BCO.

^gAverage value.

^hCalculated from relative peak intensities in the MALDI-TOF spectra.

ⁱA broad melting range was observed. n.o. = not observed.
