What is Effect of degradation on thermotropic cholesteric optical properties of (2-hydroxypropyl) cellulose (HPC) esters about?

## Abstract Some esters of (2‐hydroxypropyl) cellulose have been prepared and studied. Their cholesteric properties change with ageing and may disappear. Accelerated aging has been performed in order to analyze degradation processes which are relevant to the scission of the polymeric main chain and to the hydrolysis of the ester bonds which are mainly due to traces of water. The necessity of carefully elaborate purification is highlighted.
