Abstract
Preparation of a graft copolymer prepared by reacting a cellulose ester and a mono- or di-ester of maleic or a fumaric acid, thereby obtaining a cellulose derivative bearing a polymerizable double bonding, and then copolymerizing said cellulose derivative with other copolymerizable monomer(s). The invention also includes a coating composition based on thus obtained graft copolymer.
