Therefore, biodegradable copolymers of poly((R,S)-3,3 dimethylmalic acid) (PDMMLA) were prepared in order to develop a new coating exhibiting dif- ferent custom groups in its side chain and being able to carry a drug. This material will be in direct contact with cells and blood. It consists of carboxylic acid and hexylic groups used for hydrophilic and hydrophobic char- acter, respectively. The study of this material wettability and dynamic surface properties is of importance due to the influence of the chemistry and the potential motility of these chemical groups on cell adhesion and polymer kinetic hydrolysis. Cassie theory was used for the theoretical correction of contact angles of these chemical het- erogeneous surfaces coatings. Dynamic Surface Analysis was used as practical homogenizer of chemical hetero- geneous surfaces by cycling duringmany cycles inwater. In thiswork,we confirmed that, unlike receding contact angle, advancing contact angle is influenced by the difference of only 10% of acidic
