Abstract:
Cellulose esters are cured by exposure to radiation preferably followed by exposure to elevated temperatures of at least about 100. degree. C. In addition, polymers obtained from reacting certain cellulose esters with certain polymerizable silicon esters are provided. The cured cellulose esters are suitable for producing transparent parts such as contact lenses.
