Abstract:

Regioselectively substituted cellulose esters having a plurality of pivaloyl substituents and a plurality of aryl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in films, such as +A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.
