Aqueous solutions of (hydroxypropyl) cellulose, which can be either isotropic (dilute regime) or cholesteric (concentrated regime) at room temperature, exhibit reversible phase separation upon heating above ∼37 °C. The biphasic system does not gel

The polymerization of maleic anhydride and 1,3-propylene glycol was carried out using p-toluenesulphonic acid as catalyst. The percentage isomerization of maleate to fumarate has been correlated with the extension of polycondensation and the steric h

La polyesterification de l'anhydride maleique avec l'ethylene glycol catalysee par l'acide p-toluene sulfonique dans des conditions tres controlees donne un polyester lineaire insature de MN elevee. L'isomerisation cis-trans dans le milieu semble le
