If an ester bond is partly a resonance structure on the carboxyl oxygens. Would an electron-rich alpha carbon allow greater bond length. Conversely, an electron withdrawing group on the carbon of the former alcohol-carbon allow easier targeting of the ester. This might allow better breakdown to oligomeric units?
That might reduce energy required to hydrolase the ester bonds? In turn, allowing better reduction of mers, then combustion.
Just thinking polymer design.
